Design and evaluation of an observer-based disturbance rejection controller for electric power steering systems
Mehrabi, Naser; McPhee, John; Azad, Nasser L. (SAGE, 2015-08-13)The goal of this paper is to develop an observer-based disturbance rejection electric power steering (EPS) controller to provide steering assistance and improve the driver’s steering feel. For the purpose of control design, ... -
Dynamics and Model-Based Control of Electric Power Steering Systems
Mehrabi, Naser (University of Waterloo, 2014-10-03)Many automobile manufacturers are switching to Electric Power Steering (EPS) systems for their better performance and cost advantages over traditional Hydraulic Power Steering (HPS) systems. EPS compared to HPS offer lower ... -
Inverse Dynamics Modelling of Paralympic Wheelchair Curling
Laschowski, Brock; Mehrabi, Naser; McPhee, John (Human Kinetics, 2017-01-13)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’ ... -
A model-based approach to predict muscle synergies using optimization: application to feedback control
Sharif Razavian, Reza; Mehrabi, Naser; McPhee, John (Frontiers Media, 2015-10-06)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 ... -
Predictive Simulation of Reaching Moving Targets Using Nonlinear Model Predictive Control
Mehrabi, Naser; Sharif Razavian, Reza; Ghannadi, Borna; McPhee, John (Frontiers Media, 2017-01-13)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 ... -
Steering disturbance rejection using a physics-based neuromusculoskeletal driver model
Mehrabi, Naser; Razavian, Reza Sharif; McPhee, John (Taylor and Francis+NEJM, 2015-06-17)The aim of this work is to develop a comprehensive yet practical driver model to be used in studying driver–vehicle interactions. Drivers interact with their vehicle and the road through the steering wheel. This interaction ...
