Time delay compensation in bilateral teleoperation using sliding mode observer

Official URL: http://journals.tubitak.gov.tr/elektrik/index.php

In bilateral control applications, time delays in the communication channel have destabilizing effects. In this paper, a new sliding mode observer based compensation technique is presented. Disturbance observer is utilized to make this sliding observer more robust to parameter changes. Simulation and experimental results show that the proposed method is successful in avoiding instability due to time delays and providing transparency between master and slave sides.
