一种克服大范围随机扰动的全信息FUZZY控制器

AN ALL INFORMATION FUZZY CONTROLLER RESTRAINING BIG DISTURBANCE

通过对FUZZY控制器的分析,给出了一种新型的全信息FUZZY控制器,解决了影响FUZZY控制器控制精度的问题即系统信息丢失问题。该FUZZY控制器的设计方法较传统的FUZZY控制器简单。仿真结果表明,用该方法设计的FUZZY控制器对大范围随机扰动克服效果较好。

Through analysis of a fuzzy controller which is usually used, a new type qf all in-formation fuzzy controller is given out. So a problem which affects fuzzy controller'scontrol accuracy is solved, i. e. the problem of system information loss. To the designof all information fuzzy controller, it is convenient to realize controller design to differ-ent change range of deviation and deviation derivative. The design method is simplerthan that of traditional fuzzy Controller. By computer simulation, big range random dis-turbance can be restrained.
