Abstract :
In order to reject disturbance from the variation of load, an estimation method for load parameters for PMSM is presented to online identify moment of inertia and load torque. This method is based on model reference adaptive system through Popov´s Hyper stability criteria. The two quantities are essential for the PI controller to be adaptive for maintaining the system´s robustness. The simulation and experimental results verify the effectives of the proposed method.
