Abstract�� It is difficult to establish mathematical mode for AC servo system , because it has several disadvantages, such as parameters varying as time, load disturbing, motor being non-linear, and so on. Fuzzy control need not establis h the mathematical mode of controlled plant, but steady state precision is bad. A fuzzy-PID double mode controller was presented, which combined fuzzy controlle r and PID controller. Different controller was adopted in different domain, so th e double mode controller combined the advantages of fuzzy controller and PID con t roller, and get rid of the disadvantages of them. The double mode controller is easy to realize. Experiment results show that the fuzzy-PID double mode controller reduces settling time by 33.7% without overshooting and decreases tra cking error by 47.2% in comparison to standard PID controller.
