  • A method of automatically extracting and optimizing fuzy rule base is presented. Firstly, it applies the method of CCM (Cell-to-Cell Mapping) to analyze the evolving trend and global behavior of the closed-loop fuzzy dynamical system based on a cell state space. Secondly, each rule base is evaluated to determine a performance index according to the control objective. Thirdly, GA (Genetic Algorithm) updates the old population of coded rule bases using the performance index of each rule base generation by generation. A complicated nonlinear system---an inverted pendulum is simulated to illustrate the details of the algorithms and the results demonstrate the validity of the method.
