مدل سازی و شبیه سازی طراحی حسگر نرم برای برآورد سرعت واقعی، اندازه گیری و کنترل موتور القایی

This paper deals with the design of a speed soft sensor for induction motor. The sensor is based on the physical model of the motor. Because the validation step highlight the fact that the sensor cannot be validated for all the operating points, the model is modified in order to obtain a fully validated sensor in the whole speed range. An original feature of the proposed approach is that the modified model is derived from stability analysis using automatic control theory.
