【摘要】：近年来,包括双三相异步电机在内的多相电机凭借其转矩脉动小、可靠性高等优点,得到越来越广泛的应用。针对一种以双三相异步电机为核心的电动汽车电驱动系统,为使其在具备无速度传感器运行能力的同时,在起动及低速工况下具备良好的带载能力,该文对空间矢量分解方法得到的电机模型中谐波子空间模型的凸极效应进行了分析。在此基础上,该文提出采用反相高频注入方式,在电机两套三相定子绕组中注入大小相同,相位相反的高频信号,通过跟踪谐波子空间中由磁路饱和引起的高频定子漏磁路的凸极,实现一种基于定子磁链定向的无速度传感器控制算法。在一对拖机组上完成的相关实验,验证了所提算法的有效性。结果表明,采用该文算法,可以使电机在低速甚至零速工况下,具有稳定的高转矩输出能力。
[Abstract]:In recent years, including the double three-phase asynchronous motor, multiphase motor with its small torque ripple, high reliability, is widely used for an electric vehicle with dual three-phase asynchronous motor as the core of the drive system, in order to have any ability to run speed sensor at the start and at the same time, low speed has good load capacity, harmonic subspace model motor model based on space vector decomposition method to get the saliency effect is analyzed. On this basis, this paper adopts reversed-phase high frequency injection method in motor two sets of three-phase stator winding into the same size and opposite phase high frequency signal by tracking the stator, high frequency harmonic subspace caused by magnetic saturation of the magnetic leakage of the salient pole, a stator flux oriented speed sensorless control algorithm based on a set of drag in. The related experiments are done to verify the effectiveness of the proposed algorithm. The results show that the algorithm can make the motor have stable and high torque output capability at low speed or even zero speed.
