The Study on Self-Tuning And Multimode Intelligent Controller

In this paper, a self-tuning-multiode intelligent controller is proposed, this new controller is extensively and thoroughly studied through digital and analog-digital hybrid simulation. The fuzzy logic algorithm is applied to self-runing of PID parameters, the modified Z-N method is combined to fuzzy self-tuning and the PID parameters is tuning on line. The classical PID controller is replaced by multimode intelligent controller which consists of fuzzy controller, Bang-Bang conrtoller and PID controller This multimode controller make the system have excellent dynamic and steady index. The result of digital simulation and hybrid simulation illustrate the controller is robust and effective.
