【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。更多还原

【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 current-sharing method into the parallel system. Meanwhile,in order to improve the dynamic and steady-state 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 steady-state performance has improved under the infuence of fuzzy PI controller, which has broaden the range of application of the system.更多还原
