摘要：为解决两台开关磁阻发电机并联运行时输出电流不均衡等问题，将目前常用的数字均流法应用到开关磁阻发电机并联均流控制中。同时为了提高并联系统的动态与稳态性能，分析了并联系统结构，在此基础上设计了一种基于此方法的模糊PI控制器，设定了模糊规则，利用Matlab/Simulink搭建了模糊PI控制器的仿真模型，并将其应用到均流环中。仿真结果表明，在模糊PI控制器的作用下，并联系统的动态和稳态性能均得到了提升，扩宽了系统的应用范围。

Abstract: In order to solve the output current imbalance when two Switched Reluctance Generator(SRG) working at the parallel situation ,this paper put the mostly used digital currentsharing method into the parallel system. Meanwhile, in order to improve the dynamic and steadystate performance of this system, this systematic model was analyzed, on this basis, this paper designed a fuzzy PI controller based on this currentsharing method and set up fuzzy rules for this controller. Matlab/Simulink was used to build simulation model of fuzzy PI controller which was applied to the flow equalize cycle. Simulation results show that both dynamic and steadystate performance has improved under the infuence of fuzzy PI controller,which has broaden the range of application of the system.
Key words: switched reluctance generator；current sharing；fuzzy PI control；simulation
