In order to improve the reliability and adaptability of control system induction motor, a speed sensorless vector control system for induction motor based on DSP (TMS320F240) is presented. Combined with a rotor flux and speed observer based on a PI model reference adaptive system (MRAS), a speed sensorless field-oriented control (FOC) system for induction motors is introduced. The motor speed is estimated based on the difference between two flux estimators. The proposed control method… CONTINUE READING
