| 摘 要： | 传统标准角度控制方式下,电励磁双凸极电机(doubly salient electro-magnetic motor,DSEM)存在较大的转矩脉动。为减小转矩脉动影响,进一步研究DSEM在风力发电、航空航天等领域的应用,对DSEM转矩脉动产生的机理进行深入分析,并在转矩脉动分析基础上,提出新型转矩内环和新型转矩分配2种控制策略以抑制换向转矩脉动。以2kW、12/8极DSEM为例进行了仿真验证,并对2种控制策略进行比较。结果表明,与传统控制方式相比,采用所提出的新型转矩控制策略可以有效地抑制DSEM转矩脉动。

| Abstract: | The doubly salient electro-magnetic motor (DSEM) suffers from significant torque ripples when working with the traditional standard angle control method. To alleviate the effects of the torque ripples for further applications such as wind power generation and aerospace, in-depth analysis of the ripple generation mechanism and two novel strategies of the inner torque loop and torque distribution control were presented. In conclusion, simulation and comparative analysis of the two strategies were conducted wi... |
