| 摘 要： | 转矩脉动是开关磁阻电机(Switched Reluctance Motor,简称SRM)驱动系统中存在的一个突出问题。在SRM非线性电磁特性的有限元计算基础上,通过直接检测系统的输出转矩和模糊逻辑补偿控制器对SRM系统的相电流进行适当补偿,减小了转矩脉动成分。对一台四相、8/6极样机进行了仿真和实验。实验结果表明,通过对相电流的补偿控制能够使转矩脉动系数减小约50%,整个电机系统的平均输出转矩也得到了明显提高。

| Abstract: | Torque ripple is a major problem of switched reluctance motor(SRM)drive system,which causes undesirable vibration and acoustic noise.A novel method of torque closed-loop and fuzzy compensation control for the SRM drive system based on finite element model is described.With the proposed control concept,a compensating signal is added to the phase current,the current shape can vary with the fuzzy control ruler to minimize the torque ripple.In the end,an example of 8/6 poles SRM is simulated and tested,the resu... |
