摘    要:船舶航向控制器设计一直是船舶运动控制的重要研究课题之一,它与船舶航行的经济性、安全性和舒适性密切相关。由于船舶的动态具有大惯性、大时滞和非线性等特点,且受模型参数摄动以及船舶运动中风、浪、流等外界干扰的影响,使得控制器的设计成为一个复杂的问题。研究船舶航迹跟踪控制问题,采用自适应模糊控制方法,设计船舶航迹跟踪控制器。应用Matlab仿真工具以一条模型船为对象,对设计的控制器进行计算机仿真研究。仿真结果表明:船舶实际航迹能够跟踪期望航迹,达到满意的效果,验证所设计控制器的有效性。

Abstract: The design of ship course controller is one of the most important research topics of ship motion control, which is closely related to the economic, security and comfort of ship. Because of the high inertia, strong time lag and non-linearity characteristics, the model parameter perturbations, as well as the effects of wind, wave and current disturbances, designing a high performance ship course controller is always a very complex issue. The ship trajectory tracking control was investigated. The ship trajectory tracking control was designed by the adaptive fuzzy control method. Eventually, the simulation studies for a replica were carried out by utilizing Matlab toolbox. The simulation results are satisfied that the actual trajectory of the ship can track the desired one and the effectiveness of the controller is verified.
