Design of Sliding Mode Controller for the Position Servo System

摘要：

This paper mainly discusses a control algorithm basing on the principle of the sliding mode variable structure control for the position tracking servo system. The method for obtaining switching function and control function is also given. Finally, a hyperbolic tangent function is employed to accelerate the reaching phase and reduce chattering. It can achieve accurate servo tracking in the presence of the disturbance and the plant parameter variation. Simulation results show that the new control algorithm exhibits the better control performance than the classical control method, and the rapidness and robustness of the system are improved.
