| 摘 要： | 随着负载电流的增大,电机的磁路会进入饱和状态,传统的线性电流模型无法准确辨识电机磁链,因此凸极同步电机磁链观测模型中必须考虑饱和效应的影响。针对凸极同步电机转子结构不对称,通过实验得到的d轴饱和曲线无法完整表述电机的饱和效应,本文采用了一种q轴折算思想,将凸极同步电机转化为隐极同步电机,同时引入稳态饱和电感、动态饱和电感及交叉饱和电感。并在此基础上提出了考虑磁场饱和效应的凸极同步电机混合气隙磁链观测模型及其矢量控制策略。仿真和实验结果表明所提直流励磁凸极同步电机矢量控制解决方案具有优良的控制性能,以及很高的理论与应用价值。

| Abstract: | The magnetic circuit in the motor is saturated easily when the load current increases and thus the motor flux can not be accurately identified by traditional linear current model.Therefore,salient pole synchronous motor flux observer model must consider the saturation effect.Because of rotor structural asymmetry in saliency synchronous motors,d axis saturation curve,which obtained by experiment,can not be fully expressed saturation effect of the motor.In this paper,using the q axis conversion ideas,the sali... |
