Active Disturbance Rejection Control for Teleoperation Systems with Actuator Saturation
Authors:Ling Zhao  Lei Liu  Yingjie Wang  Hongjiu Yang
Abstract:In this paper, stabilization of a nonlinear bilateral teleoperation system with time delays and actuator saturation is investigated via active disturbance rejection control (ADRC). An linear extended state observer is introduced to deal with the lumped system uncertainties. Lyapunov functions are given to prove the stabilization of the closed‐loop bilateral teleoperation system. Two Phantom Premium 1.5 HighForce (HF) robot manipulators are used in experiments to demonstrate the effectiveness of the proposed method in this paper.
Keywords:Teleoperation system  actuator saturation  active disturbance rejection control  domain of attraction
