Abstract

The paper focuses on a model reference adaptive system (MRAS) speed identification of permanent magnet synchronous motor (PMSM) using the sliding mode approach. The new MRAS algorithm is based on the error between the outputs of flux linkage-current model and flux linkage-voltage model. Then, the error is used to estimate rotor speed by a suitable adaptation mechanism. Moreover, the sliding mode technique is used to MRAS based control of PMSM, which is more robust to motor parameter uncertainly, model inaccuracy and external disturbance. Compared to the conventional MRAS method, the new method has a much better dynamic, steady state performance and robustness. Simulation results show the validity of the proposed method.
