Abstract
Real-time optimization is conducted for a control device having a fuzzy inference system that can optimize characteristics of the control device in real time, by coding parameters used in the fuzzy inference system into chromosomes, and optimizing in real time the output of the control device by subjecting the chromosomes to evolutionary computation. Coding is conducted by (i) revising a matrix of fuzzy rules used in the system by extracting a section from the matrix and coding elements of the section into chromosomes; (ii) modifying the configuration of the fuzzy rule matrix defined by membership functions by coding elements of the membership functions into chromosomes; or (iii) changing a level of an input of the parameters and a level of an output of the fuzzy inference system.
