摘要 提出了在两相旋转坐标系下建立永磁同步电机数学模型和空间磁场定向矢量控制方法,并论述了电机定子参数与电流控制器参数设计之间的关系。在此基础上,提出了几种简单的永磁同步电机参数离线辨识方法,定性地分析了引起电机参数变化的因素和电机参数变化对控制性能的影响。以永磁同步电机为研究对象,主要离线参数辨识方法包括直流伏安辨识法、瞬态响应电机直交轴电感辨识法和频域响应电机直交轴电感辨识法。并且就不同电机直交轴电感辨识方法做了详细的对比分析,分别介绍了各种方法的优缺点。以英飞凌XMC4200单片机为核心,设计了系统硬件平台和相应的软件平台。 This paper states the relationship between motor parameters and the design of current controller parameters.On the basis,this paper presents several simple methods of PMSM parameter off-line identification.And the experimental principle and process of each method are analyzed in detail.Then this paper analyzes qualitatively the factors that result in the change of motor parameters and the effect of motor parameters variation on control performance.
