摘要
研究了数字化UPS逆变系统中采用重复控制策略,分析了重复控制的优缺点,进而采用PI控制与重复控制的复合控制,并采用MATLAB/Simulink进行了仿真研究.结果表明这种改进的重复控制策略具有优良的控制效果,对各种负载输出电压谐波失真度小.
Repetitive control techniques applied in inverter system in digital UPS is studied. It analyses the performance of repetitive control techniques and studies the compound control of PI control and repetitive control . It has studied by simulation used MATLAB/simulink softwave. The result shows that the repetitive control can effectively take control of the power supply of sine invertor. What＇s more,it works well.
