摘　　要：针对船舶操纵过程存在非线性、慢时变特性,设计了一种参数自整定模糊PID航向跟踪控制器,可以在线实现PID参数的调整,使控制系统的响应速度快,超调量减少,过渡过程时间大大缩短,振荡次数少,具有较强的鲁棒性和稳定性。Maneuvering process of ship is a nonlinear and slow time-variable one in which the conventional PID adjuster is unsatisfying. A tracking controller of self-tuning fuzzy PID is designed and proposed. For this kind of controller, the PID parameters is automatically adjusted. According to ship dynamic states, with the performances of quick response and small overshoot, the simulation shows that the performance of robustness and stability is realized with the controller.
