The problem of controlling the induction motor π-model with magnetic saturation is considered using an adaptive controller with stator current and rotor speed measurement. The new in this paper that in the previous work, only the rotor resistance and load torque can be adapted using the controller but in this work, using artificial intelligent technique, an adaptation of the stator resistance variation...
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...
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...
In this paper, we studied the vector control with orientation of rotor-flux by using PI regulators for an induction machine without speed sensor, and with adaptation of the rotor resistance. The rotor speed is estimated by using the model reference adaptive system approach (MRAS). This method consists of using two models. The first one is the reference model and the second is an adjustable one in...
