A heuristic approach to determine the gains of a fuzzy PID controller
Dave Misir, Heidar Malki, Guanrong Chen · 1996
This paper presents, to the best of our knowledge, the very first attempt in automatically determining the gains of a fuzzy PID controller.The approach is a heuristic one.The dosed-loop or open-loop response of the plant to a unit-step input change is first observea~ and then relevant parameters are determined from these responses.The fuzz~ PID controller gains are then determined from an appropriate combination of these parameters, which gives an equation that can be u~ed to find the controller gains.Computer simulations are provided to demonstrate the feasibility of this approach for tuning the fu2~ PID controller.In addition, a fug~ PID controller that is used to control a DC motor is tuned by the methods presented here.
