Design of Turntable Servo Control System Based on Sliding Mode Control Algorithm

Abstract

With the development of national defense weaponry and equipment level, higher requirements are put forward for the servo control system. The traditional PID algorithm is difficult to satisfy the target; this paper proposes a sliding mode control algorithm. Firstly, the working principle is analyzed, the DC motor model is established, the sliding mode controller is designed, and the boundary layer method is used to weaken the chattering of sliding mode control, the Stribeck friction model is used at the same time, and the simulation and experimental results is given. The experimental results show that the tracking error of the sliding mode control is 0.36° and the tracking error of the PID control is 0.675° under the same conditions, the results show that the sliding mode control algorithm is better than the PID control algorithm in the robustness and tracking performance.
