摘　　要：根据船舶操纵控制过程中 ,存在非线性、慢时变、复杂干扰的特点 ,设计了一个带模糊积分的船舶航向模糊控制器 ,使船舶在干扰变化情况下 ,模糊控制不仅能较好地实现航向保持 ,而且能获得较好的操纵性能 ;仿真结果表明 ,带模糊积分的船舶航向模糊控制器的控制比常规During the ship maneuvering, there are some characteristics of nonlinear, slow time varying and influence of complex disturbance. A kind of fuzzy controller with fuzzy integrator for keeping ship course is proposed. The controller not only can keep ship's course, but also can improve the maneuvering performance under the change of disturbance. The simulation results show that the adaptive property of the proposed fuzzy controller with fuzzy integrator is better than of the conventional PID controller.
