Abstract

A fuzzy model representation for describing the linguistic model of the object to be controlled in a control system is prompted. With the linguistic model of controlled object or process to be controlled, we can construct a close loop system representation. Consequently, we can discuss the system appearance with the assistance of the linguistic model as we do using a mathematic model in a conventional control system. In this paper, we discuss the describing ability of a fuzzy model and give a formal representation method for describing a fuzzy model. The combine method for a fuzzy system constructed by multiple fuzzy models is also discussed based on the controller model and the linguistic model of controlled object.
