Abstract
Exact information of the rotor resistance is the key to achieve high performance of indirect field-oriented control for induction motors. However, rotor resistance is time-varying when the motor works. Therefore, the effect of the rotor resistance uncertainty on control performance is analyzed, and an approximate estimator is designed based on the steady-state rotor flux. This estimator has a simple form and can improve the motor control performance a lot. Simulation results of a certain induction motor indicate that the estimator presented above is effective.
