A sensorless algorithm was developed to predict rotor speeds in an electric three-phase induction motor. This sensorless model requires a measurement of the stator currents and voltages, and the rotor speed is predicted accurately without any mechanical measurement of the rotor speed. A model of an electric vehicle undergoing acceleration was built, and the sensorless prediction of the simulation rotor speed was determined to be robust even in the presence of fluctuating motor parameters and significant sensor errors. Studies were conducted for varying pulse width modulator resolutions, and the sensorless model was accurate for all resolutions of sinusoidal voltage functions.
开发了一种无传感器算法来预测三相感应电动机中的转子速度。这种无传感器模型需要测量定子电流和电压,并且无需对转子速度进行任何机械测量就能准确预测转子速度。建立了一辆正在加速的电动汽车的模型,并且确定即使在电机参数波动和存在显著传感器误差的情况下,模拟转子速度的无传感器预测也是稳健的。针对不同的脉宽调制器分辨率进行了研究,并且该无传感器模型对于正弦电压函数的所有分辨率都是准确的。
