基于遗传规划的协调控制系统控制器设计

根据大型火电机组的协调控制系统被控对象的特性,提出了一种基于遗传规划的控制器设计方法。该方法不同于传统的多变量控制器设计方法,将多变量控制问题转化为多个单变量控制问题来考虑,而是通过遗传规划算法直接搜索适合于协调控制被控对象的最优控制律,从而使得闭环对象具有良好的控制品质,满足现场高质量的要求。并且采用遗传规划算法还可以得到适用于同样对象的PID控制器,也具有很好的控制品质,通过对两种控制器的控制效果进行比较,进一步说明遗传规划算法在控制器设计上的可行性。

Coordination Control System Controller Design Based on Genetic Programming

A controller design method in view of genetic programming is proposed on the basis of controlled objects speciality of the large-scale electricity units.This method is different from the design method of traditional multivariate controller that transforms multivariable control problem into multiple single variable control problem,it searches the optimal control law fit for the coordination control object,thus closed-loop object has a good quality that meets the high quality requirements.The genetic programming algorithm is used well to get PID controller object that applies the same objects.It further states genetic programming algorithm on the feasibility of the controller design by comparison of the two controllers control effect.
