摘　　要：针对提升电-机械转换器快速响应特性的技术需求,提出了新型三线圈结构电-机械转换器。通过建立的电-机械转换器数学模型,提出采用细菌觅食算法来寻找时间最优解,并基于此方法设计了砰-砰与比例-积分双模控制器。分析与仿真结果表明,相对于传统单线圈电-机械转换器,采用双模控制器的三线圈电-机械转换器,其响应时间从8.5 ms缩短至2.5 ms,震荡和超调不超过5%,可知该技术能够实现响应特性,前景良好。In order to improve the response performance of electro-mechanical converter（EMC）, a novel EMC device with triple coils was investigated in this paper. Mathematical model of the proposed EMC was fi rstly established. By applying the Bacterial Foraging Algorithm, an optimal solution for the model can be obtained. Adual-mode controller with Bang-Bang proportional-integral was designed based on the proposed method. Analytical and simulated results showed that, response time of the triple coil EMC driven by dualmode controller can be reduced from 8.5 ms to 2.5 ms. In comparison with conventional single coil EMC, the ringing and overshoot can be controlled within 5%.
