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 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...
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 کاملSensorless Speed and Position Control of Induction Motor Drives
Controlled induction motor drives without mechanical speed sensors at the motor shaft have the attractions of low cost and high reliability. To replace the sensor, the information on the rotor speed is extracted from measured stator voltages and currents at the motor terminals. Vector controlled drives require estimating the magnitude and spatial orientation of the fundamental magnetic flux wav...
متن کاملMRAS based Speed Control of sensorless Induction Motor Drives
Senseless induction motor drives are widely used in industry for their reliability and flexibility, particularly in hostile environment. However, the performance of many of previously developed observer based speed sensors in very low speeds of IM drives was not satisfactory. In this paper we present two types of MRAS based speed estimators, one based on the rotor flux and the other based on th...
