摘　　要：针对传统滑模观测器低速性能差的问题,提出一种带定子电阻辨识的五相感应电机滑模速度观测器,实现宽范围的五相感应电机无速度传感器运行。建立五相感应电机在旋转坐标系下的电压方程,基于此方程将五相感应电机解耦成基波平面与三次谐波平面分别独立控制。谐波面上构建第一滑模观测器用于实现电机定子电阻和转子转速在线辨识。在此基础上,将第一滑模观测器辨识结果加载至基波面上的第二滑模观测器,实现转子电阻和转子时间常数在线观测,继而有效克服温度、集肤效应等因素对转子参数的影响,进一步提高无速度传感器运行性能。实验结果验证了所设计双滑模观测器无速度传感器技术的有效性和实用性。The performance of the traditional sliding mode observer at low speed is poor.To solve this problem,a sliding mode speed observer for five-phase induction motor with stator resistance identification is proposed to realize the wide range speed sensorless operation.The voltage equation of the motor inrotating coordinate system was established.Based on this,the motor was decoupled from the fundamental plane and the three harmonic plane independently.On the harmonic plane,first observer was constructed to realize the online identification of stator resistance and rotor speed.And on the fundamental plane,identification results of the first observer were loaded on the second observer to realize the online observation of rotor resistance and time constant,and then the effect of temperature and skin effect on the rotor parameters were effectively overcome to further improve the performance of the speed sensorless.Experimental results verify the effectiveness and practicability of speed sensorless technology with double sliding mode observer designed in this paper.
