TL;DR: In this paper, the state of the art on high-precision motion control techniques is surveyed by referring to recent publications, mainly in the transactions and conferences of the IEEEIndustrial Electronics Society (IES), where a 2-degree-of-freedom (DoF) control framework is considered a practical and promising approach to improving motion performance.
Abstract: In this article, the state of the art on high-precision motion control techniques is surveyed by referring to recent publications, mainly in the transactions and conferences of the IEEEIndustrial Electronics Society (IES), where a 2-degree-of-freedom (DoF) control framework is considered a practical and promising approach to improving motion performance. The actual issues and relevant solutions for each component in the 2-DoF control structure are clarified. Next, one of the examples, a 2-DoF controller design for robust vibration suppression positioning, is presented as an application to industrial high-precision positioning devices. Precise modeling and identification for the target mechatronic systems should be indispensable from the standpoint of more accurate model-based feedforward compensation and/or more progressive design of feedback controllers.

TL;DR: A product modeling framework and a CAD system for conceptual design of complex products focusing on hierarchical system decomposition and consistency management of design information across different engineering disciplines is proposed.
Abstract: Conceptual design of modern products has become complex due to an increasing number of subsystems and components comprising the system and the multi-disciplinarity of the employed design knowledge. The paper proposes a product modeling framework and a CAD system for conceptual design of complex products focusing on hierarchical system decomposition and consistency management of design information across different engineering disciplines. The framework and CAD system support these tasks with concurrent development of functional and parameter-level product descriptions and comprehensive evaluation of these descriptions from functional, parameter-level, structural, and behavioral aspects. A conceptual design case at a printer manufacturer is demonstrated.

TL;DR: Substantial in the SPES modeling framework, although the type of abstraction is not specified further, the role concept significant for the automation can be depicted with a functional viewpoint and implementation relationship, though an explicit type of artifact is missing: role or abstract component.
Abstract: ion High High Is substantial in the SPES modeling framework, although the type of abstraction is not specified further. For example, the role concept significant for the automation can be depicted with a functional viewpoint and implementation relationship, though an explicit type of artifact is missing: role or abstract component. Modularization Med. High Modularization has to be applied in the SPES modeling framework when hierarchizing. However, the consideration and specification of a hierarchy-wide modularization, such as is implemented in the automation domain with the aid of the group concept (logical areas), is lacking. This would correlate to a viewpoints and cross-aspect viewing aggregation. Disciplinespecific views Med. Med. The viewing concept is implemented in the SPES modeling framework entirely. The discipline-specific design, however, is not sufficiently supported. Aspects allow the internal classification of information within a component, though not an explicit component-wide classification or summary of individual aspects, interfaces, and connections. Dependency Low Low The mapping concept with the characteristics implementation, allocation, and link to external data is currently not fully specified. For example, extensions for the representation of complex dependencies with class, features, and functionality are required. Reuse None High The SPES modeling framework does not currently provide a reuse concept. Libraries, instance, and inheritance are required to support the reuse of engineering artifacts. Mechatronics None Med. Artifacts are classified in the SPES modeling framework. However, in automation, an artifact frequently comprises information from multiple viewpoints that must be considered cohesively because a significant added value of the modeling arises. In automation engineering, firstly the system requirements are analyzed (decomposition). As explained by means of the case study, requirements are not only based on functions of the functional viewpoint, but also on elements of additional viewpoints. That means that a sequential arrangement of the design within a viewpoint or a level is not sufficient. The use of a parallel process instead allows temporal overlapping of the design activities of the different disciplines involved. In addition, it must be possible to integrate solution elements while increasing the level of abstraction (bottom-up). This results in the process flow as shown in Fig. 11-9 (right).

TL;DR: The architecture and algorithms of MFI are reviewed, and some implementation examples in industrial automation and robotic applications are presented and the most frequently used algorithms in previous researches with their advantages and limitations are summarized.
Abstract: The objective of this paper is to review the theories and approaches of multisensor fusion and integration (MFI) with its application in mechatronics. MFI helps the system perceiving changes of the environment and monitoring the system itself. Since each individual sensor has its own inherent defects and limitations, MFI merges the redundant information acquired by multiple sensors synergistically to provide a more accurate perception and make an optimal decision in further. The wide application spectrum of MFI in mechatronics includes the industrial automation, the development of intelligent robots, military applications, biomedical applications, etc. In this paper, the architecture and algorithms of MFI are reviewed, and some implementation examples in industrial automation and robotic applications are presented. Furthermore, sensor fusion methods at different levels, namely, estimation methods, classification methods and inference methods, the most frequently used algorithms in previous researches with their advantages and limitations are summarized. Applications of MFI in robotics and mechatronics are discussed. Future perspectives of MFI deployment are included in the concluding remarks.

TL;DR: The control logic of the system is composed from autonomous controllers of the IMCs and is automatically verified using model-checking and Net Condition Event Systems formalism is used to model the decentralized control logic and discrete-state dynamics of the plant.
Abstract: This paper introduces an approach to automatic verification of mechatronic systems designed as plug-and-play of Intelligent Mechatronic Components (IMC). The control logic of the system is composed from autonomous controllers of the IMCs and is automatically verified using model-checking. Net Condition Event Systems formalism (a modular extension of Petri net) is used to model the decentralized control logic and discrete-state dynamics of the plant. A re-configurable pick and place robot is used as an illustrative example. At first a three cylinder pick and place robot is used to design our new master-slave architecture for controller design and then the NCES models are re-used without much modification in a new 6 cylinder pick and place robot. The control model is then subjected to model checking using the ViVe/SESA model checker. A multi closed loop model of Plant and Controller is used and controller is extensively verified for safety, liveliness and functional properties of the robot. Computational Tree Logic (CTL) is used to specify these properties.

TL;DR: A group project‐based approach for enabling teams of students to complete mechatronics projects and a set of heuristic guidelines is proposed, which have yielded high student satisfaction and achievement.
Abstract: This study presents an innovative group project-based approach to teaching mechatronics. Mechatronics is a complex, highly technical and multidisciplinary field involving the design and manufacture of integrated products. Mechatronics course at the undergraduate level is rapidly increasing across the world. Most courses require student teams to design a product. The complexity of student projects can make administration of mechatronics courses extremely difficult. Students develop both practical and theoretical understanding of mechatronics while working on group projects. They also develop the interpersonal and communication skills needed to work in a multi-disciplinary field. This study describes a group project-based approach for enabling teams of students to complete mechatronics projects. A set of heuristic guidelines is also proposed. At the National Changhua University of Education in the Department of Industrial Education and Technology, this approach has yielded high student satisfaction and achievement. © 2010 Wiley Periodicals, Inc.

TL;DR: In this paper, high-gain adaptive controllers for minimum-phase systems with relative degree one or two, known sign of the high-frequency gain, bounded disturbances and state dependent, functional perturbations are presented and developed for "minimum-phase" systems.
Abstract: High-gain adaptive control and its applications in mechatronics are discussed. The high-gain adaptive controllers are presented and developed for "minimum-phase" systems with relative degree one or two, known sign of the high-frequency gain, bounded disturbances and state dependent, functional perturbations. System identification or parameter estimation is not required for controller implementation. Structural system knowledge is sufficient. The robust controllers guarantee tracking with prescribed asymptotic or transient accuracy and, in combination with a proportional-integral internal model, may assure steady state accuracy. Finally, the controllers are applied for speed and position control of stiff and flexible industrial servo-systems and it is shown that high-gain adaptive position control with prescribed transient accuracy of rigid revolute joint robotic manipulators is feasible, if the inertia matrix is known.

TL;DR: An energy optimal control strategy for a highly maneuverable Robotic Electric Vehicle (ROboMObil) is presented and an CA extension to nonlinear dynamic inversion is discussed, which is able to compensate the different time constants of the actuators.
Abstract: In this paper an energy optimal control strategy for a highly maneuverable Robotic Electric Vehicle (ROboMObil) is presented. The ROMO is a development of the Robotics and Mechatronics Center (which is part of the German Aerospace Center) to cope with several research topics, like energy efficient, autonomous or remote controlled driving for future (electro-) mobility applications. Since saving electric energy is a primal goal when operating a battery electric vehicle (like the ROMO), we have developed a new approach for energy optimal control of an over-actuated electric car. The focus of the control strategy lies in the model based minimization of the actuator losses and power consumption for driving along a precalculated trajectory to optimize the overall efficiency. The approach is based on a real-time capable nonlinear control allocation (CA) algorithm, using quadratic programming, implemented in the object oriented modeling language Modelica. Two optimization objectives are analyzed and the performance is presented by simulation results. Finally an CA extension to nonlinear dynamic inversion is discussed, which is able to compensate the different time constants of the actuators.

Abstract: In the current paper the design-centric approach for mechatronics and smart product design is presented. The novel aspect of theproposed solution is a comprehensive learning concept and environment which includes remote labs, mobile hardware,methodology, learning material and web environments. The whole concept supports fast and student-oriented learning process foracquiring knowledge and practical skills of integrated systems. The concept is applied into practice in the course of several stages.The most recent case study is described in this paper and the course setup proposed. The feedback from students indicates the timespent by the student on the activity, when the course follows the proposed concept. It is apparent that students spend considerablymore time than the curriculum requires. At the same time, workload of the supervisor is lower. However, the quality and learningoutcomes are higher than those of previous related courses, but without using novel technologies. In the current paper specialattention is paid to remote and virtual labs related to the proposed learning concept.

TL;DR: This paper discusses the development of a 4D optimal flight trajectory based on aircraft performance, weather forecasts, Air Traffic Control database and aircraft operational data, and Dynamic Programming is utilized in the optimization process.
Abstract: An efficient, reliable and futuristic Air Transportation System (ATS) is the key to handle the anticipated rapid changes in the aviation industry over the next few decades. Trajectory Based Operations (TBO) could be considered as one of the most significant solutions to cater for these problems. This paper discusses the development of a 4D optimal flight trajectory based on aircraft performance, weather forecasts, Air Traffic Control (ATC) database and aircraft operational data. Dynamic Programming is utilized in the optimization process for its qualities of avoiding iterative calculations, predicting the required amount of calculations and feasibility of applying inequality constraint conditions. Optimal flight trajectories were generated for a single aircraft for its climb, cruise and descent phases in a provided 4D grid platform based on a busy domestic flight route, between Tokyo (Haneda) and Fukuoka. Flight data were recorded on a commercial GPS data logger inside an airliner cabin and used to compare with optimum solutions obtained from the model. Consumed fuel consumption and flight time were evaluated to understand the benefits gained by the optimization.

TL;DR: There is an urgent need to intensify multidisciplinary research in this novel domain of interest, and that new pre-implementation demonstration, prototyping and empirical testing methodologies are also needed.
Abstract: In the last two decades, an intense shift Irom advanced mechatronics systems to cyberphysical systems is taking place. The former systems, which integrate mechanical, electronics, computing, control and situated reasoning components, are typically implemented as closed, predefined, controlled, and deterministic systems. The latter systems are characterized by open system boundaries, large functional and structural complexities, self-learning and -reasoning capabilities, partial autonomy, context-driven adaptability, and decentralized decision making. As the latest trend, they are getting more extensively embedded in the fabric of society. First, the episodes of the observable physical, biological, social and technological evolution are overviewed from the aspect of the place and role of information. Then, the distinguishing characteristics of cyberphysical systems are analyzed and the currently on-going transition to social-cyberphysical systems is dealt with. Finally, the paper discusses nine major design challenges raised by the social-cyber-physical system paradigm. As major design challenges: (i) handling aggregative complexity, (ii) static and dynamic compositional synergy, (iii) dynamic and evolutionary operation in time, (iv) multi-abstraction based modeling, (v) system integrity verification and behavior validation, (vi) dynamic scalability towards meta-systems, (vii) transformation of big data, (viii) testable surrogate prototyping, and (ix) robust social compliance are discussed. I f we want to address these challenges successfully, then new design principles and system design methodologies need to be developed. The main propositions are that there is an urgent need to intensify multidisciplinary research in this novel domain of interest, and that new pre-implementation demonstration, prototyping and empirical testing methodologies are also needed.

TL;DR: The state of the art of integrating risk and reliability studies with SysML in the design process of safety-critical systems is presented and an Electro Mechanical Actuator system for light aircraft is used to illustrate the integration process.
Abstract: Model-based system engineering is an efficient approach to specifying, designing, simulating and validating mechatronic systems. This approach allows errors to be detected as soon as possible in the design process, and thus reduces the overall cost of the product. Uniformity in a complex mechatronic project, which is by definition multidisciplinary, is achieved by expressing the models in a common modeling language such as SysML. This paper presents the state of the art of integrating risk and reliability studies with SysML in the design process of safety-critical systems. An Electro Mechanical Actuator system for light aircraft is used to illustrate the integration process, showing how a failure modes and effects analysis is automatically carried out from SysML structural and behavioral diagrams. Through our industry-relevant case study, the advantages and drawbacks of the employed integration methodology are analyzed.

TL;DR: In this article, the authors describe synergistic mechatronics design, sensing, and control of a scaled active wind tunnel, which establishes a practical foundation for atmospheric display in virtual environments.
Abstract: Creating wind within virtual environments (e.g., wind display) is a challenging problem with a potential to develop immersive atmospheric display for virtual reality systems. This paper describes synergistic mechatronics design, sensing, and control of a scaled active wind tunnel, which establishes a practical foundation for atmospheric display in virtual environments. Our approach combines numerical simulations and physical experiments in order to achieve geometric design of the physical system while simultaneously developing simplified control laws using limited sensing and computational resources. As experimental results indicate, several physical modifications and unique sensor and control law developments are necessary to achieve controlled wind flow in a physical system. These results validate system performance over a wide range of wind speeds and angles, which serves as a basis for future development of full-scale virtual reality systems with atmospheric display.
