The Comparative Study And Combination Of Fuzzy Control And Classical Control

This article compared the fuzzy control and the classical control in certain scale and certain degree. We made a study of the two type of control means and the combination of them and in the same time we made some improve on them. We made some constructive conclusion through the simulation comparison. The mostly work of this article is following: First: we compared the fuzzy control and PID control(classical PID, the optimal PID, variable gain PID) and made out the excellence and the disadvantage of them. Then we explain the Mamdani fuzzy controller and the variable gain PID controller in theory. Second: we compared the fuzzy control and the optimal control, then explain the characteristics of them. Third: in allusion to several conditions we compared the fuzzy control and adaptive control(STR), then we got the utility scale of them. Fourth: we studied a known means of improving the performance of the fuzzy control and explain the excellence and the disadvantage of it. Then we put forward a means of tuning the proportion factor and explain it in theory.
