A controller designing method optimized by GA and H ∞

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。

This paper introduces a controller designing method optimized by GA and H ∞.The H ∞ loop shaping technique is applied in this method. Also, the genetic algorithms are employed to optimize the loop shaping weighting functions. This method can not only make the controller designed with good robustness, meet the requirement of specifications, but also make the controller designing procedure simpler. The effectiveness of such method is illustrated by the application to the design of ship course keeping controller.
