摘要针对分析得到的磁链估算误差,提出用来修正磁链估算误差的定子回路等效电阻R_eq校准方法。在建立开关磁阻电机(SRM)电感模型的基础上,首先通过实验完成等效电阻R_eq的校准。然后在SRM控制系统中,通过在线检测方法获得电机磁链数据,将测量得到的磁链离散数据贮存于控制器的RAM中。最后,通过数据分析处理,得到优化后的电感参数。实验结果证明该方法简单高效,能够实现SRM高性能控制。

Abstract：In view of the flux linkage estimation error through analysis,a method is proposed in order to calibrate the equivalent resistance (R_eq),which can revise the estimation error.In this paper,the inductance model of the SRM is built first.And then R_eq is calibrated through experiments.After that,in the SRM control system,the received data of the flux linkage from online testing is stored in the RAM of the controller.At last,the inductance parameter is calculated through data analysis.According to the experimental results,this method is proved to be simple,effective,and can realize high performance control of SRM.

Key words： SRM inductance model flux linkage estimation equivalent resistance
