“…In order to increase the performance of the control system, one of the researchers' concerns is taking into consideration phenomena such as the magnetic saturation, the dependence of motor parameters on temperature and the iron losses [14], [18], [19]. As an adaption method for the estimation of the rotor time constant, the online tuning of this constant is proposed in [18], by using the voltage model of the induction motor, which does not depend on rotor time constant, as the rotor flux reference model.…”

In [19], based on the steady state model of the electrical drive, it is proposed to eliminate the rotor time constant from the control algorithm.…”

Characterized by very good performance in both steady-state and dynamic regimes and also by a relatively simple control structure, the induction motor control with rotor flux orientation is frequently adopted in electric drive systems, especially in electric traction applications. This paper analyses the possibilities of rotor flux estimation in a real Romanian electric traction system of locomotives. Thus, to estimate the magnitude of rotor flux and the angu-lar position of the rotor flux vector, two possibilities are identified and discussed. First, the use of the sensed speed and stator currents is taken into consideration, and then the use of the measured supply voltages and the stator currents is the second alternative. Dedicated algorithms were designed for their related control. Both variants are analyzed through the results of the simulations obtained based on the specific models created in the Matlab/Simulink software. Four values of the imposed speed are taken into account in the performed analysis. It is highlighted that, in real conditions where the drive system is provided with speed sensor and there is no sine filter for the distorted motor supply voltage, the best option to estimate the rotor flux is to use the measured speed and the stator currents.
