Abstract :
This paper deals with the flux estimation for induction motor drives. The equations for the parameter sensitivity of both the flux estimation and the torque production are derived for a full-order flux observer. Based on the parameter sensitivity analysis, a very simple method to determine a robust observer gain combining the current model and the voltage model is proposed.
