Systematic Synthesis of an Optimal Fuzzy Controller
Li Pin · Control theory & applications · 1995
The fuzzy logic controller has been shown its power in ill-defined or nonprecise systems.However there are still some shortcomings.Two of them are that the control rules of fuzzy controller could not ho always made optimal and that no systematic method is available for acquiring fuzzy control rules.In this paper,a systematic design procedure of an optimal fuzzy controller is presented.This controller will have the form of an ordinary fuzzy controller and make the fuzzy performance index minimum,which is similar to the quadratic performance index.This method is applied to a papermachine control system and the control result is very satisfsctory.
