Abstract

In the low speed region, it is difficult to estimate the rotor speed of the induction motor, because the machine parameter (especially R 2) has a strong influence to the speed estimation. It is known that the simultaneous estimation of the speed and R 2 is impossible. In this paper the R 2 estimation in the transient state without adding any additional signal to the stator current is proposed, and the R 1 is estimated from the instantaneous reactive power. These algorithms are verified by the digital simulations and the experiments.
