摘　　要：阐述了多性能指标综合下的遗传算法在控制器参数寻优上的应用,讨论了算法的具体实现方法,其中指标综合可以有多种方式,具体介绍了对指标的加权方法。最后,通过与单一性能指标约束的遗传算法的仿真结果进行比较,证明新方法具有更好的参数寻优能力。Genetic algorithm with many performance indexes is proposed. It can synthesize seek optimally application in the controller parameters. And the concrete implementation method of the improved genetic algorithm is discussed. In the improved genetic algorithm, the constructed formula of many performance indexes is also given and the aspect of formulation have discussed. Genetic algorithm with many performance indexes has many the representation ways, one of which is involved in simulation. The selection of the performance index has considered the coefficient of weight in order to display the important of every performance index. Compared to the simulation result of the genetic algorithm with single performance index, have proved new method have better parameter seek optimally ability.
