摘　　要：研究了数字化UPS(Uninterruptible Power Supply)逆变系统中应用数字伺服控制技术,给出了数学建模的方法,并采用MATLAB/Simulink进行了仿真研究。结果表明,数字伺服系统的控制原理能有效地控制UPS正弦逆变电源,逆变器输出稳定、波形畸变小、抗负载干扰能力强。Digital servo control techniques was studied applying in inverter system of digital UPS--Uninterruptible Power Supply, and the approach of mathematic modelling was probed into, which was studied by simulation using MATLAB/simulink softwave. The results show that the control principle of digital servo system can effectively take control of the power of UPS sine invertor, which has stabile output, low voltage distortion and strong load disturbing resistance.
