摘　　要：针对传统的PI控制存在响应速度慢、参数整定困难等问题,提出一种模糊自适应双闭环控制系统,通过模糊控制实时整定电压外环PI控制参数,优化控制效果。仿真结果表明,相对于传统的双闭环控制,模糊自整定双闭环控制具有较强的自适应性,不仅提高了系统的动态响应性能,同时也能有效抑制母线电压的波动,提高了系统的抗干扰能力,增强了鲁棒性。For traditional PI control,such as slow response speed and difficult parameter setting,a fuzzy adaptive double closed-loop control system is proposed in this paper.In the system PI control parameters of voltage outer loop can be adjusted in real time,so as to optimize the control effect.Simulation results show that compared with the traditional double closed-loop control,the fuzzy self-tuning double closed-loop control has strong self-adaptability.It can not only improve the dynamic response performance of the system,but also can effectively reduce the fluctuation of the bus voltage and promote the robustness of the system.
