Fuzzy controller using multiple rule bases

A new architecture of rule base which is used in multiple inputs fuzzy controller is proposed. Multiple inputs system is very common in practice and it always needs a high order control system to acquire high performance which leads to a multi-dimension rule base for a fuzzy logic control system. High order rule base is not only difficult to understand for human being but difficult to be built and implemented. This paper suggests a new architecture for fuzzy controller to handle the high order process control by using low dimensional rule bases. And the new controller uses the rule base to solve the stable error problem that bothering conventional fuzzy logic controller also. In this way we can reduce the number of control rules and make it easy to be understood and carried out. This paper explains the architecture of the new rule base and discusses the implementation on a practical system.
