| Abstract: | In view of effects of the parameters of fuzzy controller with nonlinear scaling factors on a system''s performance and interaction between parameters, this paper proposes a method based on genetic algorithm (GA) to tune and optimize the parameters. Simulation results show that systems which adopt the parameters derived from the method are better in dynamics and static property. When the parameters or the structure of plant is changed, a fuzzy controller with nonlinear scaling factors can maintain good performance indicators through re-tuning the parameters and has stronger robustness. |
