Implementation of Hard Real-Time Embedded Control Systems

Abstract: Although the domain of hard real-time systems has been thoroughly elaborated in the academic sphere, embedded computer control systems –- being an important component in mechatronic designs –- are seldom dealt with consistently. Often, off-the-shelf computer systems are used, with no guarantee that they will be able to meet the requirements specified. In this paper, a design for embedded control systems is presented. Particularly, the paper deals with the hardware architecture and design details, the operating system, and high-level real-time language support. It is shown how estimates of process run-times necessary for schedulability analysis can be acquired on the basis of deterministic behavior of the hardware platform.

Integrated real and virtual prototyping

Automated performance assessment of mechatronic motion systems during the conceptual design stage

Abstract: In the conceptual design stage of electro-mecha nical systems, a mechatronic design approach can be applied successfully. Automated mechatronic design support has been developed on basis of an existing design method for a large class of mechatronic systems. This method determines the functional interaction between different domain specific subsystems. Automated model reduction and model simplification algorithms are applied to convert the system model of a proposed design into the standard form required by this method. The results of this design method, feasible parameter values for the proposed design, can be assigned to the components in the model in an interactive way. The developed design support puts emphasis on the interpretation of the results instead of the application of procedures. It quickly provides insight in the design problem and estimates feasible goals and required design efforts at an early stage.

MERIT 2000-a new concept in power engineering education

Abstract: This paper suggests an extensive use of simulation technology to enhance student's understanding of the fundamentals, as well as practical solutions while making this approach quite effective in reducing overall classroom teaching time. This is achieved by efficiently presenting and explaining the analytical and practical aspects of related phenomena through simulation, as well as by redistributing some of the teaching to the laboratory environment. This approach will make sure that an additional time in the curriculum is made available for introduction of the new topics that will reflect the multidisciplinary issues created by the changing environment.

Conceptual Design for Controller software of mechatronic systems

Abstract: The method and software tool presented here, aims at supporting the development of control software for mechatronic systems. Heterogeneous distributed embedded processors are considered as target hardware. Principles of the method are that the implementation process is a stepwise refinement from control laws to efficient computer code and that all phases are verified by simulation. Simulation is also used as verification tool during physical-system modelling and control law development. Data flow diagrams are used as description language for controller implementations, whereas the physical-system models are expressed in bond graphs. Future work comprises the building of the complete tool, although individual parts are ready.

Human integration in simulation

Abstract: In this paper we discuss the effectiveness of "immersing" a human-in-the-loop virtual realistic simulation process. Simulations are a vital part in the design process where the designer can optimize the characteristics of a product before they are fabricated. The vehicle driving simulator is taken as the illustration of the need for considering the human interface of a simulator that emulates performance of automotive mechatronics systems. Issues and use of human immersion in evaluating the simulated products are discussed.

A transparent and flexible development environment for rapid design of cognitive systems

Abstract: This paper describes a novel design environment for cognitive systems tailored to the needs of flexibility, speed and transparence demanded in numerous application domains as, for example, automated visual inspection for quality control, mechatronics, medical applications, and other cognitive tasks. Our QuickCog design environment combines methods from statistical pattern recognition, neural networks, image and signal processing, and exploratory data analysis. The main features of the design environment are visual programming, interactive sample set compilation and sample set oriented processing, automatic feature selection, automatic processing method selection and parameter optimisation, feature space visualisation, and powerful self-configuring classifiers. QuickCog is available on PC/Windows'95.

Applied Mechanics in Science and Engineering

Abstract: This article traces the development of applied mechanics and its relation to science and engineering by reviewing first the history of mechanics from 1600 to 1900, the physics of the 19th century, and the engineering education in the same period. The review is followed by a discussion on modern physics and modern engineering, and the formation of applied mechanics as a discipline in science and one in engineering, which is classified into 94 subjects in 10 categories by Applied Mechanics Reviews. The article concludes with a chart to summarize the relation between science and engineering, and the interactions of applied mechanics with other disciplines. There are 15 references included in this article.Originally published in Applied Mechanics Reviews, Vol. 51, No. 2, February 1998

Engineering Graphics And Computer Aided Design: A Foundation To Engineering Design And Analysis

Abstract: With the advent of solid modeling, the importance of engineering graphics has been emphasized. Many employers hiring engineers expect their new engineers to have some solid modeling expertise from their academic experience. As with many engineering schools, engineering graphics was greatly curtailed at Rensselaer during the 1980’s. When engineering graphics was reintroduced at Rensselaer as a required freshmanengineering course in 1991, there were two major goals. The first was to teach the fundamentals of engineering graphics using solid modeling as opposed to a user course in the specific solid modeling software. The second goal as to provide the students with an opportunity to use solid modeling as an engineering tool for conceptual design, detailed design and engineering analysis.

Distributed HIL simulation for the design of decentralized control structures

Abstract: In technical systems of the future the combination of local components from different technical disciplines with local information processing will increase. One example is a series hybrid vehicle. It consists of an auxiliary power unit, e.g,. an internal combustion engine, and a generator coupled to the crank shaft of the combustion engine, a battery and a drive unit with two electric motors. Each of these vehicle units has its own electronic control unit. Design and interplay of distributed intelligent aggregates in future technical systems will gain ever more importance. Parallelisation will be used not only for the purpose of reaching real time, but also for structuring purposes. The aim of mechatronics is the overall design of those systems. A toolset which supports the distributed HIL simulation as part of the mechatronic design cycle will be presented.

Actuator concepts and mechatronics

Abstract: Mechatronic design implies the consideration of integrated mechanical, electrical, and local control characteristics in electromechanical device design. In this paper, mechatronic development of actuation device concepts for active aircraft aerodynamic flow control are presented and discussed. The devices are intended to be embedded in aircraft aerodynamic surfaces to provide zero-net-momentum jets or additional flow-vorticity to control boundary layers and flow- separation. Two synthetic jet device prototypes and one vorticity-on-demand prototype currently in development are described in the paper. The aspects of actuation materials, design approaches to generating jets and vorticity, and the integration of miniaturized electronics are stressed.
