摘要：
The paper presents a detailed analysis of the impact of stator winding faults on the properties of the rotor flux estimation in the vector controlled induction motor drives. In the paper the two well-known simulators, often used in the industrial drives, were analyzed. The tests were carried out in a Direct Field Oriented Control (FOC) system. It was shown, that during inter-turn short circuits, the vector controlled system can be even unstable. To guarantee the stability during stator faults, a compensation method, based on the modified rotor flux estimators, was proposed. The article presents a detailed theoretical analysis as well as the results of simulations carried out in the MATLAB/Simulink environment.
