关于Fuzzy调节器的积分作用

本文讨论了在Fuzzy调节器中引入积分作用减少稳态误差的问题.Fuzzy调节器引入积 分作用后,一般也不能保证稳态误差严格趋于零,但可以使稳态误差小到足以满足工程要求. 文章提出了对误差信号的"Fuzzy值"积分的方法以兼顾动、静态性能.数字仿真表明方法是 可行的.

On Integral Action of the Fuzzy Controller

The problem of introducing integral term in a fuzzy controller to reduce steady state error is considered. It is pointed out that, in general, the error can not be completely eliminated by the fuzzy controller even integral action is applied; however, the error can be made so small by the controller as to be accepted in ,applications. A method of integrating the "fuzzy value" of the error signal to take cure of both dynamic and steady performances is proposed, which is proved reasonable by digital simulation.
