Optimization Of Fuzzy Controller And Its Application In The Thermal Engineering Process Control In Power Plants

The principles and implements of the existing optimizing fuzzy control by Gas methods thoroughly are summarized. And then PAM method according to merit of Pittsburgh and Michigan Approach is presented to optimize FLC. This method can improve evidently efficiency and quality of evolution because of combining rule- control grade evolution and global-local evolution . At the end of the thesis, the PAM is employed into an outlet temperature control system for superheaters of a certain boiler unit. The results of simulations show that the PAM method can effectively shorten amount of rule of FLC for optimizing FLC based on ensuring performance the temperature control system .Yang Zhenyong (Thermal Power Engineering) Directed by Associate Prof. Sun Jianping Prof. Yu Xining...
