摘要
基于对永磁同步电机d-q坐标系模型的分析,利用伺服驱动器本身的硬件资源,提出了一种永磁同步电机主要参数的辨识策略,实现电阻、交直轴电感、反电势系数等参数的辨识。在一台1.2 kW的永磁同步电机上进行了实验,完成了上述参数辨识,并在辨识参数的基础上设计了电流环调节器。得到的辨识参数具有较高的精度,验证了所设计的辨识策略的有效性,具有一定的工程实用意义。
With the analysis of PMSM d-q coordinate system model, a kind of identification strategy for PMSM parameters was designed based on servo drive hardware, which could realize the identification of resistance, inductance of d-q axis and back EMF coefficient. The experiments of parameter identification were performed on a 1.2 kW PMSM and the current loop controller was designed with these parameters. The high precision of identification shows the validity of the identification strategy which has certain practical significance.
