Abstract:

The gain-scheduling variable structure tracking control for a class of nonlinear systems with uncertainties  is studied. A new controller is proposed which uses the switch function to schedule the sliding mode, the layer and the approach rate. Based on the new control rule, the control system can improve the control performance, such as restraining the chattering, decreasing the cost of the control power, and keeping a allowable stable error. The simulation results demonstrate the effectiveness of the proposed approach.
