| Abstract: | According to the simplified model of electromechanical actuator, a variable structure controller based on exponential approach law was put forward in this paper. The existence, arrival and stability of the sliding mode were proved. The sign function was used to reduce the chattering. The simulation results showed that the controller using the variable controller bad quick response and more robust to disturbing compared to the pole placement method, which was simple structure and easy to be implemented. |
