There are a large number of people with movement disorders who have difficulties doing their daily tasks independently. Much research has been devoted to the therapy of these people, and rehabilitation robots have been developed to assist with therapy. In robotic rehabilitation, since the human body is interacting with a mechanical device, safety issues in(More)
This paper presents a new model-based method to define muscle synergies. Unlike the conventional factorization approach, which extracts synergies from electromyographic data, the proposed method employs a biomechanical model and formally defines the synergies as the solution of an optimal control problem. As a result, the number of required synergies is(More)
— Nowadays many automobile manufacturers are switching to Electric Power Steering (EPS) for its advantages on performance and cost. In this paper, a mathematical model of a column type EPS system is established, and its state-space expression is constructed. Then three different control methods are implemented and performance, robustness and disturbance(More)
Paralympic wheelchair curling is an adapted version of Olympic curling played by individuals with spinal cord injuries, cerebral palsy, multiple sclerosis, and lower extremity amputations. To the best of the authors' knowledge, there has been no experimental or computational research published regarding the biomechanics of wheelchair curling. Accordingly,(More)
This article investigates the application of optimal feedback control to trajectory planning in voluntary human arm movements. A nonlinear model predictive controller (NMPC) with a finite prediction horizon was used as the optimal feedback controller to predict the hand trajectory planning and execution of planar reaching tasks. The NMPC is completely(More)
The aim of this work is the creation of a realistic driver model to help develop new technologies to aid drivers in the execution of their driving tasks. A realistic driver model can reduce the time-consuming trial and error process of designing products, and thereby reduce the vehicle's development time and cost. The overall goal of this research is to(More)
This paper presents a methodological approach for the application of virtual prototyping for the evaluation of the intelligent vehicle active suspension system performance. In this approach, a full passenger car model is developed using ADAMS software. In the modeling approach, not only the suspension components are precisely modeled, but also modeling of(More)
