The performance of the induction machine driving system with indirect vector control can easily be influenced by the effects of parameter mismatch and eddy current, which result that the magnetizing component of stator current can't align with the rotor flux vector, especially in the range of high speed and flux weakening. In order to achieve accurate rotor flux orientation, a novel control strategy...
This paper presents a closed loop control technique for harmonic content reduction in the stator current of an induction machine feeded with a three phase inverter, within a velocity control loop. Using a digital filter for Clarke transformation, a robust sliding flux observer, and a closed loop control for the zero sequence of a SVPWM three phase inverter, this work shows how the proposed schema...
