Integral sliding mode control of a bilateral teleoperation system based on extended state observers

A novel control scheme has been proposed to solve the synchronization control problem for a nonlinear bilateral teleoperation system with time delays in this paper. An extended state observer is introduced to deal with the lumped system uncertainties. Both fast convergence rate and high convergence precision are guaranteed via designing an integral sliding mode controller. Some general Lyapunov stability criteria are given for the nonlinear bilateral teleoperation system with time delays. Lastly, two Phantom Premium 1.5 HF robot manipulators are used in the experiments to demonstrate the effectiveness of the developed techniques in this paper.
