Structural Analysis of Nonlinear Fuzzy Controller Based on PI/PD Control
Jun Liu · Journal of Qingdao University of Science and Technology · 2005
In this paper ,we give a study of the input-output structures of fuzzy controllers with nonlinear input fuzzy sets. The study focuses on some common fuzzy controllers and proves the analytical structure of fuzzy controllers related to PID controllers,on the one side,it reveals that fuzzy controllers are better than PID controllers in practice, the other it offers us the method to design steady fuzzy system by judging the gain relationship between them. The simulation to the fuzzy control is better than ordinary nonlinear PI/PD control.
