专家系统在GP设计非线性系统控制器中的应用

摘要

According to a series of nonlinear systems,the expert system is used to design nonlinear system controller based on the original parameters optimization of controller by using genetic programming algorithm,the controller is designed to meet the high quality requirement of control.The results show that the control quality of controlled plants has been highly improved when the expert system is added and the parameters of the fitness function are determined by prior knowledge.%针对于一类非线性对象,在原有遗传规划算法实现控制器参数寻优的基础上,引入专家系统,指导和优化控制器参数寻优过程.其目的一方面是设计的控制器能够满足更高质量的控制要求,另一方面加快寻优过程,缩短寻优时间.仿真结果表明,引入专家系统,利用先验知识确定适应度函数的参数,能够使被控对象具有更加优秀的控制品质.
