Development and applications of general-purpose fuzzy controllers

Determination of control rules and selection scaling factors are two key aspects in the design of fuzzy controllers. The relationships between scaling factor and dynamic response of the system are analyzed, and the influence of each scaling factor on control processes is discussed. Based on these, a general-purpose fuzzy controller (GPFC) by amending scaling factors has been developed. The controller has been used in the metallurgical, fiberglass, and cigarette producing industrial processes in China for years. The results show that GPFC has the potential to be widely applied in industrial process control and may solve some of the control problems which can not be solved by traditional regulators
