A stable robust impedance controller is proposed here for mobile manipulators with time-delay compensation, for handling uncertainties and disturbances in the presence of nonholonomic constraints, nonlinear dynamics, and the coupling of mobile...

Recently, the variety of devices and robots are available for recovering and rehabilitating human disorder patients. In this paper, simple and effective control method utilized for position-impedance control. This method consists of two parts...

In this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. The majority of existing control approaches are based on control torque strategy, which require...

used is torque-based impedance control. This paper presents an electromyogram-based robust impedance control for a lower-limb rehabilitation robot using a voltage-based strategy. The proposed control strategy uses surface electromyogram (sEMG) signals...

In this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is proposed. Most existing control approaches are based on control torque strategy, which require the knowledge of robot...
