摘要：
This paper proposes a novel voltage reconstruction method for sensorless induction motor drives based on model reference adaptive system (MRAS). The instability of discrete motor model under low calculation frequency in high-power traction system is analyzed in this paper. The proposed method can eliminate the error of the stator voltage applied in the discrete model when the calculation frequency is increased to higher than the switching frequency and further improve the accuracy of the speed estimator. Simulation and experimental results are given to demonstrate the effectiveness of the proposed voltage reconstruction method.
