Bilateral force sensorless control based on finite‐time adaptive sliding‐mode‐assisted disturbance observer

IET Control Theory & Applications, 2021
Bilateral teleoperation systems are widely used to compensate for image spin and in many other applications. Good transparency (position tracking and force feedback) is an important performance index in the control design of bilateral teleoperation ...
