Synchronized control for teleoperation with different configurations and communication delay

Abstract

This paper deals with a control for teleoperation with different configurations and communication delays. We propose a synchronized control with individual gains and power scaling in the task space. In this method, the end-effector motion and force relationship between the master and slave robots can be specified freely in the task space and the control gains can be independently selected appropriately for the master and slave robots. The delay-independent asymptotic stability of the origin of the position and velocity errors is proven by using passivity of the systems and Lyapunov stability methods. The proposed control law achieves synchronization with power scaling. Several experimental results show the effectiveness of our proposed method. © 2007 IEEE.
