Abstract

Control methods are represented for the AC servo system of the brushless director motor. The paper determines fast and precise performance perfectly with the help of a position regulator and a speed regulator. The nonlinear position control regulator and the variable structure fuzzy PID speed control regulator are designed and the control algorithms are proposed. The simulation result and operation shows the improved performance of the system: the robustness is better than conventional PID control under the parameter variable and load disturbance
