Sliding Mode Control Technology Research About Underwater Vehicle Servo

Abstract

To improve the mobility of underwater vehicle and interference capability of servo control system, the paper designed the variable structure control rate of underwater vehicle servo with the sliding mode variable structure control technology. The paper established servo control model and system simulation was carried out as an example of a certain underwater vehicle. Compared with the traditional PID control, the simulation results show that the control system using sliding mode variable structure has fast response speed, small overshoot and strong anti-interference ability, better stability. The results show that this method can improve the performance of servo control system.
