Abstract
This paper investigates the global robust output tracking control problem via output feedback for a classof nonlinear uncertain systems with the integral input-to-state stable (iISS) dynamic uncertainties. By performingthe coordinates transformation and employing an extended state observer (ESO), it can be seen that the robust setpointtracking control is well solved. The proposed control strategy simplifies the control design procedure. Thiscontrol scheme finds its application in the mass-spring mechanical system. It is shown that the asymptotic trackingcontrol for any desired displacement can be achieved in the mass-spring mechanical system in the case of unknownparameters. The simulation results demonstrate that the proposed control scheme has a better tracking performance. This verifies the effectiveness of the developed method.
