On Design of Fuzzy Controller Expressed by Fuzzy Rules with Singleton Consequents

TSK fuzzy system can represent effectively the behavior of a complex nonlinear system with a low number of rules as a linear system with the desired accuracy and guarantee the stability of the closed loop system, while the interpretation of the rules is difficult due to the functional nature of the consequents. On the contrary, fuzzy controller with sungleton consequents is understandable intuitively and adjustable the rules easily due to linquistic expression of the rules. Ideally, one would like to combine the positive identification properties of TSK fuzzy system with the advantages of fuzzy controller with singleton consequents. Therefore, this paper suggests a method for designing fuzzy controller with singleton consequents by using TSK fuzzy system when the behavior of a nonlinear system can be described a singleton fuzzy model by human expert.
