抄録

In the very low speed region, it is difficult to estimate the rotor speed of the induction motor, because the machine parameter (especially R₂) has strong influence to the speed estimation. It is known that the simultaneous estimation of the speed and R₂ is impossible. In this paper proposed are the R₂ estimation in the transient state without adding any additional signal to the stator current, and the output voltage compensation without the voltage sensors. The R₁ is estimated from the instantaneous reactive power.
