PID (Proportional Integral Differential)regulator has been widely used in ship autopilot. According to the lack of overshoot, response speed in the traditional PID, it proposes a way to design ship course self-tuning fuzzy PID autopilot which combines conventional PID control and fuzzy control. Then according to some indicators which contain overshoot, tracking response speed, control accuracy and so on a new evaluation method which can exam the performance of autopilot has been proposed. We test the performance of the autopilot both by using Matlab, and by using intelligent control of the ship simulation platform which is developed by our research teem to simulate. Compared with the performance of conventional PID autopilot concludes that the fuzzy self-tuning PID autopilot has better performance than the conventional PID autopilot.
