摘　　要：采用控制和实现方法是决定UPS逆变器输出波形质量和动态性能的主要因素。提出了一种模糊自适应PI双闭环的控制方案,并用MATLAB对系统进行了建模仿真验证。仿真实验结果表明,该方法能实现逆变器的快速动态响应性能和高精度稳态输出波形,满足了UPS对高性能输出电压波形的需要。Generally,the key factor which determines the output waveform quality and dynamic characteristics of UPS inverter are what kind of control method is selected and how the control law is implemented.A novel control method is put forward,which is based on fuzzy adaptive PID and Double-loop.The simulation on an inverter based on MATLAB were implemented.The result show that the system can achieve fast transient responses and higher output voltage waveform.This control scheme is best suited for UPS applications where high performance voltage waveforms are needed.
