Application of fuzzy control theory

The basic feature of the conventional control is that the design of the controller is based on the mathematical model of the object,but in many cases,the precise mathematical model of controlled object is difficult to establish,while the control method of combining the fuzzy control with other technologies is able to obtain better control effects for the multivariable,nonlinear and uncertain and complex systems.This paper gives an overview of the development of fuzzy control theory,and introduces the technology of combining the fuzzy control with the other control methods and the current urgent problems and prospects of fuzzy control.
