Abstract

Different advanced sensorless techniques have been proposed based on the model reference adaptive system (MRAS) principle to make the interior permanent magnet synchronous motor (IPMSM) drives mechanically more robust. However, in the special application such as high-power traction systems, the difference between the switching frequency and the calculation frequency is large, and the inconsistency between the command voltage and the actual voltage will affect the accuracy of the MARS estimator. To overcome such a drawback, this paper proposes a novel voltage reconstruction method to improve the accuracy of the MRAS estimator. Simulations and experiments are conducted to verify the effectiveness of the proposed method. Combining with the proposed algorithm, the problem of the inconsistency can be solved, and an accurate rotation estimation can be realized.
