Abstract :
This paper deals with the problem of robust speed control of electrical servodrives. A robust controller is developed using a nonlinear PI controller. The controller nonlinear characteristics is obtained due to fuzzy logic technique application. An original method of controller settings adjustment is presented. The use of this adjustment procedure ensures robust speed control against the variations of the moment of inertia. Simulations and laboratory results validate the robustness of the servodrive with permanent magnet synchronous motor
