【Abstract】 In this paper,a self-adjusting fuzzy controller is designe d, which adjusts the fuzzy rule base according to adjusting the parameters of the fuzzy controller and the weights of each input variable by the values of input v ariables. the self-adjusting fuzzy controller is used as the speed controller o f a AC servo system. The experiment results prove that the method can not only improve general fuzzy controller’s steady-state precision and dynamic performan ce ,but also obtain strong robustness which PID controller never obtains.更多还原
