摘　　要：以下垂控制法微电网逆变器为研究对象,对传统电压环采用的PI控制器进行了改进,提出了一种采用模糊PI控制器的电压环设计方案。模糊PI控制器结合了模糊控制技术和PI控制器的优点,使微电网逆变器并联系统的抗干扰能力和鲁棒性能得到显著提高。最后利用Matlab/Simulink进行仿真,仿真结果验证了所提出的模糊PI控制的正确性和有效性。Based on the study of micro-grid inverters with droop control methods,a novel control strategy of fuzzy PI control applied to the voltage loop was proposed in order to improve the traditional PI controller.Fuzzy PI controller has a better adaptability and control precision because it combines the advantages of fuzzy control and PI controller.The application of fuzzy PI significantly increases the robustness of paralleling operation of inverters in microgrid system.Matlab/Simulink was used to simulate this strategy and the results indicate fuzzy PI control is correct and efficient.
