The application of multi-criterion satisfactory optimization in fuzzy controller design

This paper presents a new approach to the fuzzy controller design. After review of standard fuzzy system operation, a new optimization model called multi-criterion satisfactory optimization model is presented. The disadvantages of traditional membership functions and controller rule base optimization are introduced. The approach that uses multi-criterion satisfactory optimization model in fuzzy controller design is illustrated with several control systems. The results of simulation demonstrated our method is useful for the fuzzy controller design.
