Abstract :
It is well known that hysteresis often exists and failures may occur in practical actuators during system operation. The compensation for uncertainties caused by unknown hysteresis and unknown failures is an important problem in ensuring system stability and performances. However, available results based on adaptive approaches to address such a problem are still very limited. In this paper, an adaptive tracking control scheme is proposed to solve such a problem. Simulation results also illustrate the effectiveness of the control scheme.
