Design and Control of a Small-Clearance Driving Simulator

Abstract: This paper presents a driving simulation whose aim is twofold: (1) to investigate the possibility of reducing motion clearance to achieve compact and low-cost driving simulators and (2) to evaluate multimodal and immersive virtual reality motion restitution in platooning driving The choice has been made for a driving simulator having at least two degrees of freedom (DOF) These consist of the longitudinal displacement and seat rotations The simulator is also equipped with a force feedback steering wheel for virtual drive assistance These components are gathered on a serial kinematics-type platform to facilitate a control scheme and avoid the architecture complexity A comparative study was made to devise a motion cueing strategy, taking into account both the psychophysical and technological constraints Experimentations were carried out for several case combinations of the longitudinal displacement and seat rotations

Motion cueing algorithms for small driving simulator

Abstract: This paper deals with motion control problem for a 2 DOF small driving simulator. The main idea is to test and compare performances of different washout algorithms applied to such platform category. The experimentations allow us to have the best compromise between quality of the perception (sensation), implementation complexity and platform architecture. Implementation of different washout algorithms (optimal, adaptive and classical one) are discussed. Only the longitudinal restitution is studied. The results show that there is not significant differences between these approaches using with platform type. The lack of pitch DOF in our simulator does not allow a restitution of the sustained acceleration and no coordination between longitudinal and pitch channels may be done

Mechatronics, Design, and Modeling of a Motorcycle Riding Simulator

Abstract: This paper describes a new motorcycle riding simulator whose purpose is twofold: 1) it can be used as a training tool for new riders in different scenarios, such as a normal traffic environments or in dangerous riding situations (avoidance, emergency braking, nearly failing or slipping situations, and bad weather conditions) and 2) it can be used to study motor cyclist behavior in such situations and rider-motorcycle interaction. Our studies have led to the development of an original five DOF mechanical platform including double haptic feedback on the handlebar. The remaining components are the basic movements consisting of pitch, roll, and yaw. These components are gathered in a parallel kinematics-type platform to enhance the movement bandwidth of the two-wheeled riding simulator. Despite its simplicity, the particular appeal of this simulator lies in the possibility of reproducing important motorcycle movements and inertial effects, which allow for the perception of sensations close to reality. The motivation behind the choice of platform movements and system actuation are described. Also, theoretical issues (modeling, identification, and control aspects) and performance results are provided.

Observer design for two-wheeled vehicle: A Takagi-Sugeno approach with unmeasurable premise variables

Abstract: This paper is dedicated to the problem of observer design for Takagi-Sugeno (T-S) nonlinear systems with unmeasurable premise variables (TSUPV) and application to autonomous bicycle system. The main idea is based on the use of differential mean value theorem combined to the sector nonlinearity transformation. The objective of this approach is to make the state estimation error dynamic on a T-S form which allows to apply the classical Lyapunov analysis to derive convergence conditions. The design algorithm is proposed in terms of linear matrix inequalities (LMI). To illustrate the proposed methodology, a nonlinear bicycle model is considered.

Classic and Adaptive Washout Comparison for a Low Cost Driving Simulator

Abstract: The paper deals with control of small driving simulator SIM comparing the useless of adaptive and classic approaches. Driving simulators are considering as an interactive virtual reality tools, which take a considerable place in the human factors studies. The difficulty to reproduce in reality some drive situations mainly for risk and reproducibility reasons increases the interest of this tool. Nevertheless, the validation of the experiments carried out on driving simulator is closely related to embedding realism of the driver in the simulated world. In this article, we present the design of a low cost and small motion platform, which allow the restitution of 2 DOF movements. This overall system is considered as two independent systems linked mechanically. The first system consists in motorized rail for the longitudinal movement while the second system consists in motorized seat allowing either pitch movement of this one or just back seat inclination (this case would not be discussed in the rest of paper)

Telemanipulation with Time Delays

Abstract: In this paper we survey the development of the wave variable concept and examine wave-based teleoperation. We study the behavior of force reflecting systems under unknown but constant transmission delays, ranging from periods less than the human reaction time to several seconds. Passive transmission procedures guarantee system stability, but wave reflections and spurious dynamics may interfere with normal operation. Using wave variables for the analysis and implementation, and making appropriate design choices, a system with consistent and predictable behavior is constructed. This design methodology aims to create a virtual tool which accounts for the implicit limitations imposed by the delay. These developments also form the basis for extensions to wave-based prediction and application to variable delays, such as those inherent to Internet-based telemanipulation.

Mechatronics기술개발 현황과 과제

Abstract: Mechatronics Technology is a growing career field that deals with the integration of mechanical and electronic components managed by control systems. Mechatronics technicians troubleshoot, maintain and repair mechanical equipment controlled by electrical, electronic and computer systems. These types of systems are increasingly used in a wide variety of manufacturing and industrial settings. Clark College's Mechatronics Technology (MTX) classes emphasize current concepts and technology by providing practical, hands-on experiences with the latest, industry standard equipment. In addition to the technical knowhow needed to maintain and repair equipment, the certificate and degree programs will help prepare students to think critically, function as a successful team member and communicate clearly too internal and external customers.

Sampled data systems passivity and discrete port-Hamiltonian systems

Abstract: In this paper, we present a novel way to approach the interconnection of a continuous and a discrete time physical system first presented in . This is done in a way which preserves passivity of the coupled system independently of the sampling time T. This strategy can be used both in the field of telemanipulation, for the implementation of a passive master/slave system on a digital transmission line with varying time delays and possible loss of packets (e.g., the Internet), and in the field of haptics, where the virtual environment should 'feel' like a physical equivalent system.
