Fuzzy control using knowledge acquired from PD control

摘要

The authors propose a design method for a fuzzy controller by using knowledge acquired from proportional derivative (PD) control. Two types of fuzzy controller are presented. One is identical and the other is approximately equivalent to the PD controller. The mathematical model of the fuzzy controller is derived and the properties of the output of the fuzzy controller are clarified. A design method of the fuzzy controller which satisfies two specifications, the dynamical properties of the rising and settling regions of the response, is presented using the mathematical model.
