论述一种ＧＡ和Ｈ∞混合优化控制器的设计方法．该方法采用Ｈ∞环路成形技术设计控制器，同时，采用遗传算法对成形加权函数进行优化，这样，既能保证设计的控制器具有强的鲁棒性，满足各种性能指标的要求，又可使控制器的设计变得简单易行．将该设计方法应用于船舶航向控制器的设计，证明了该设计方法的有效性 A design method of GA and H∞ hybrid optimization controller is discussed. In this method, the H∞ loop forming technology is used to design the controller. At the same time, the genetic algorithm is used to optimize the forming weighting function. In this way, the designed controller is robust and meets various performance requirements. The controller design can be made easy. The design method is applied to the design of ship course controller, which proves the validity of the design method
