摘　　要：基于感应电机在静止A、B、C和转子速a、b、c两种坐标系下的数学模型,推导出一种转子电阻在线识别的新方法。在MATLAB/SIMULINK环境下建立了系统的仿真模型,实例仿真验证了方法的准确性。该方法简单,且避免了奇异解的问题。A new algorithm of the online rotor resistance estimator of induction motor is developed, based on the mathematical model of induction motor in stationary ABC and rotor abe reference frame. The system simulation model is built in the MATIAB/SIMULINK environment, and the accuracy of new algorithm has been verified through example simulation. The algorithm is simple and can avoid the singularity problem.
