摘 要：为了改善UPS逆变器输出波形的质量，提出了一种新的控制方法。该方法把不同性质负载与滤波器视为一个整体，建立了统一的无差拍控制方程，通过软件判断方法实现了不同负载在线准确辨识，并可用辨识出的负载参数实时修正控制方程系数，以达到精确控制的目的。分析和仿真实验证实了该方法的有效性和可行性。

Abstract: To improve the output voltage waveform of UPS inverter, a novel control algorithm was presented. The proposed algorithm treats the load and the filter as a unified unit, the unified deadbeat control equation was built. The online load identification was realized through the software, and coefficients of the control equation were corrected instantly to exactly control. The analysis and simulation results verify the viability and effectiveness of the control algorithm.
Key words: uninterruptable power supply (UPS); inverter; deadbeat control; load identification
