摘　　要：通过分析现有基于模型参考自适应系统(MRAS)估算电机转速的原理和不足,提出一种基于滞环切换的MRAS方案辨识电机转速。理论和试验结果表明该方案具有良好的静、动态性能和较好的鲁棒性。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.
