Abstract :
According to the principle of vector control system for induction motors, we have established speed sensorless vector control system based on open-loop speed estimator and MRAS speed estimator, and simulated two models by the MATLAB. The results show both of the two estimators can meet the requirements of the system. In comparison, the stationary performance and the dynamic performance of the MRAS speed estimator are superior than open-loop.
