In the speed sensorless control of the induction motor, the machine parameters (especially rotor resistance R2) have a strong influence on the speed estimation. It is known that the simultaneous estimation of the rotor speed and R2 is impossible in the slip frequency type vector control, because the rotor flux is constant. But the rotor flux is not always constant in the speed transient state. In this paper, the R2 estimation in the transient state without signal injection to the stator current is proposed. This algorithm uses the least mean square algorithm and the adaptive algorithm, and it is possible to estimate R2 exactly. This algorithm is verified by the digital simulations and experiments.
