为提高正弦逆变电源的波形质量和系统动、静态响应性能,在正弦逆变控制中引入重复控制原理.该算法将逆变电源视作一个参考正弦信号的随动系统,建立了单相正弦逆变电源输出滤波单元数学模型.利用Madab仿真软件对算法进行了在线仿真研究,并利用DSP微控制器构建的实验平台对算法进行了实验验证.结果表明,在采用该算法所设计控制器的控制下,正弦逆变器逆变输出稳定、波形畸变小、静态抗负载干扰能力强.

To improve the sine inverter power output voltage waveform quality and its system steady-state and dynamic performance, this paper presents a sine inverter control design based on repetitive control arithmetic.The inverter system is seen as a standard sine wave servo system in the arithmetic.The mathematical model of inverter output waveform is built.The simulation and experimental results prove that the sine inverter has stable output,low voltage distortion and strong load disturbing resistance.
