A battery hardware-in-the-loop setup for concurrent design and evaluation of real-time optimal HEV power management controllers
Sharif Razavian, Reza; Lashgarian Azad, Nasser; McPhee, John (Inderscience publishers, 2013-11-03)We have developed a battery hardware-in-the-loop (HIL) setup, which can expedite the design and evaluation of power management controllers for hybrid electric vehicles (HEVs) in a novel cost- and time-effective manner. The ... -
Design and evaluation of a real-time fuel-optimal control system for series hybrid electric vehicles
Sharif Razavian, Reza; Taghavipour, Amir; Lashgarian Azad, Nasser; McPhee, John (Inderscience publishers, 2012)We propose a real-time optimal controller that will reduce fuel consumption in a series hybrid electric vehicle (HEV). This real-time drive cycle-independent controller is designed using a control-oriented model and ... -
Design and Hardware-in-the-Loop Testing of Optimal Controllers for Hybrid Electric Powertrains
Sharif Razavian, Reza (University of Waterloo, 2012-09-06)The main objective of this research is the development of a flexible test-bench for evaluation of hybrid electric powertrain controllers. As a case study, a real-time near-optimal powertrain controller for a series hybrid ... -
A Human Motor Control Framework based on Muscle Synergies
Sharif Razavian, Reza (University of Waterloo, 2017-08-23)In spite of the complexities of the human musculoskeletal system, the central nervous system has the ability to orchestrate difficult motor tasks. Many researchers have tried to understand how the human nervous system ... -
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 ...
