Accurate knowledge of most parameters is important for prices modelling and corrects operation of a number of induction motor control schemes. Stable and accurate operation of control scheme requires an appropriate on-line identification algorithm for the rotor resistance and considering of core loss. In this paper, we propose a full-order flux observer with adaptive speed loop, while core loss and...
This study presents bi input-extended Kalman filter (BI-EKF) based speed-sensorless direct torque control (DTC) of induction motors (IMs). For this aim, all states required for the speed-sensorless control system as well as commonly known parameter uncertainties related to stator resistance Rs, rotor resistance R'r, and load torque tL including also viscous friction term have been estimated by using...
In this paper, we studied the vector control, by orientation of rotor-flux by using fuzzy regulators for an induction machine without speed sensor with adaptation of rotor resistance. The speed is estimated by using the adaptive method with model of reference (MRAS). This method consists in working out two models one of reference and the control adjustable one for the estimate of two components of...
