Low Speed Sensorless Variable Structure Control of Induction Motor
Torque and speed sensorless induction motor control is presented in this paper. The idea is realized using a sliding mode closed loop rotor flux observer for estimation of electromotive force of machine. This signal is then used in nonlinear stator flux and torque control of induction motor and in rotor flux observer for speed and flux estimation. The analysis of the proposed method is included...
متن کاملSpeed Sensorless Torque Control of Induction Motor for EV's
Novel induction motor speed sensorless torque control optimizing both torque response and efficiency is proposed. The control is quite different than the conventional field-oriented or direct torque control [1]. First, the produced torque is explicitly continuous output variable of control. Second, a new rotor flux observer, which allows speed sensorless operation of IM by low and zero speed, w...
متن کاملSpeed-sensorless sliding-mode torque control of an induction motor
Novel induction motor control optimizing both torque response and efficiency is proposed in the paper. The main contribution of the paper is a new structure of rotor flux observer aimed for the speed-sensorless operation of induction machine servo-drive at both, low and high speed, where rapid speed changes can occur. The control differs from the conventional field-oriented control. Stator and ...
متن کاملSliding Mode Application in Speed Sensorless Torque Control of an Induction Motor
Induction motor speed sensorless torque control, which allows operation at low and zero speed, optimizing both torque response and efficiency, is proposed. The control is quite different than the conventional field-oriented or direct torque control. The produced torque is explicitly continuous output variable of control. A new stator and rotor flux controller/observer based on continuous slidin...
متن کاملSeveral Speed Sensorless Methods of Induction Motor Control
This paper deals with different techniques to estimate the speed intended to the induction motors field oriented controlled without a shaft sensor. The information on the rotor speed is extracted from the stator terminal measurements (voltage and current). Open loop estimators and closed loop observers are used for this purpose and compared in term of their robustness against the variation of t...
