OPTIMIZATION OF FUZZY PARTITION BASED ON EVOLUTION STRATEGY
Jiang Jing-ping · Proceedings of the CSEE · 2004
A good fuzzy system should exhibit not only good approximation, but also minimal fuzzy partition, good completeness and distinguishability. But fewer efforts have been done for the latter. So a definition for optimum fuzzy partition is proposed in this paper. Its main aspects include the minimal form and completeness-distinguishability of fuzzy partition. These conditions are added to the fitness function of the evolutionary strategy for optimizing the fuzzy system. To check the effectiveness of the suggested approach, an example for nonlinear plant control is examined. It is verified that the fuzzy system works very well, especially when the priori Knowledge are insufficient.
