In this paper, a sensorless induction motor parameter identification is presented. Sensorless control employs a variety of estimators and observers of motor speed, torque and fluxes, and accurate information about motor parameters is crucial to obtain a high performance control. The parameters of the induction motor equivalent circuit are obtained by means of DC an AC tests using the voltage-source...
For the high-performance sensor-less vector control of an induction motor, the accuracy of the motor parameters has an important impact on the performance of the whole system. In this paper, we propose a novel method for the offline identification of motor parameters. In our method, first we use DC or single phase AC as an excitation signals. Then we measure the voltage of DC bus and current of stator...
