摘要

This paper represents a small dynamic universe algorithm for achieving both high precision and real-time performance of nonlinear identification by fuzzy neural network. Two influence factors of identification precision, membership function type and numbers of fuzzy subset in the input space, are analysed with given network structure. Then a small dynamic universe algorithm is derived. Different with common fuzzification procedure, algorithm employs methods of shifting a small operating window in the input workspace to generate the initial values of premise fuzzification parameters and reducing the numbers of fuzzy subsets in the windows. So a contradiction between the high precision and real-time performance is avoided. Simulation results of nonlinear identification demonstrate effectiveness of proposed algorithm.
