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.
