초록
In this paper, We propose a variable structure controller with time varying switching surface. We calculate the maximum value of switching surface gradient under the bound of input. To enhance the robustness, we, choose a time varying switching surface gradient that is of the 3rd order polynominal form. We use evolution strategy to optimize the parameters of the switching surface gradient. Finally, the proposed method is applied to the motor position control. Simulation results show that the proposed method is more useful than the conventional variable structure controller.
