Abstract :
This paper presents a new simplified V/f control system of induction motor (IM) for precise speed operation, which is based on the vector control theory. A linear model is derived for analyzing the system stability, including the influences of motor operating states in motoring and regenerating operations, and parameter variation of low pass filter. A stator resistance identification is proposed by using d-axis current. The effectiveness of proposed system has been demonstrated by simulations and experiments.
