Abstract :
During the operation of an induction motor (IM) drive system, parameters´ vibration and external load disturbance will influence the effectiveness of control. A method using model reference adaptive system (MRAS) algorithm is presented in this paper for an online identification of load inertia. Further, by using the result of identification, automatic adjustments to the speed controller can be made. A scheme for tuning the speed controller automatically is introduced. Simulation results in both time domain and frequency domain show the usefulness of the proposed method
