| Abstract: | Based on existing Model Reference Adaptive System (MRAS), a hysteresis controlled MRAS system was proposed, which had better steady and dynamic performance in both low and high frequency range. Theoretical analysis and experiment results display that this method was feasible, and had good robustness for stator resistor. |
