【Abstract】 The paper describes a new method to optimize a fuzzy system. This method adopts RPROP algorithm to identify parameters of the fuzzy system, which eliminates the influence for partial derivative to weight changes. Combining with adaptive rule selecting method to get the number of fuzzy rules, therefore it can avoid blindness in choosing the fuzzy rules. Use this method to study on a nonlinear dynamic system, the simulation results demonstrate the efficiency and feasibility of the proposed method.更多还原
