摘　　要：鉴于零航速下船舶横摇模型的不确定性,通过在线辨识确定船舶横摇运动数学模型.在此基础上采用改进型遗传算法和单纯形法相结合的优化策略对PID参数进行优化,使优化过程既具有遗传算法的全局性又具有单纯形算法的快速性.仿真显示按此种控制策略设计的控制系统对横摇模型的不确定性具有较强的自适应性,有一定的工程应用价值.The ship dynamic model is acquired by system identification for uncertain model of ship rolling. The parameters of PID controller are optimized by Simplex Genetic Algorithm Hybrid. This new algorithm has the merits of Genetic Algorithm and Simplex Algorithm. The result of system shows that system with this controller has good adaptive ability for the uncertain ship rolling model and has engineering application value.
