Abstract

To solve the control problem of course angle, the process of ship autopilot parameter is not easy and timely. Bang-Bang fuzzy PID control method was proposed. Bang-Bang control was to maximize the use of fast ship autopilot. Fuzzy PID was used to improve the accuracy of the ship autopilot. The system static and dynamic performance were ideal. The MATLAB simulation of the Bang-Bang fuzzy PID controller and a PID controller were carried out on the ship autopilot. Results showed that: Response time of PID control was 3.4s, maximum overshoot was about 22.0%, response time of Bang-Bang fuzzy PID was 0.72s, and maximum overshoot didn´t exceed 2.11%.The stability accuracy and rapidity of the system were able to satisfy the navigation technical requirements.
