Abstract
In this paper, we attempt to control induction motors with high dynamic performance by means of decoupling of motor speed and rotor flux. For power efficiency control or field weakening, the rotor flux may be reduced at light loads. Motor inductances depend on rotor flux but not on machine temperature. So, if the rotor flux is to be changed for power efficiency control or field weakening, the motor inductances should be changed according to the rotor flux commands. On the other hand, rotor resistance varies greatly with the machine temperature. We present novel identification algorithms for motor inductances and rotor resistance. Our identification algorithms are computationally simple and have very small identification errors. To demonstrate the practical significance of our results, we present some simulation results as well as mathematical analysis.
