摘要
通过对电压、电流双环反馈控制和重复控制方法在中频正弦波逆变电源中的控制特点进行分析,总结了两种控制方法的优缺点。为了提高中频逆变电源输出正弦波的品质,研究了一种基于以上两种控制方法的复合控制方法,优化了控制策略,简化了两种控制策略的控制器设计。在理论分析的基础上,完成了基于DSP的复合控制系统设计。仿真和实验结果证明复合控制具有上述两种控制方法的优点,为实现高品质的正弦波逆变器提供了一种较好的控制策略。
Through analyzing the control characteristics of double-loop feedback scheme and repetitive control scheme in this paper, the merits and demerits of the two methods are summarized. To improving the qualities of output-waveforms of the medium frequency sinusoidal waveform inverters, a novel multi- ple-control method is studied. The control strategy is optimized and the design of controller is simplified. Based on the theoretical analysis, the control system based on the DSP is achieved. The merits of the Multiple-Control are proved by simulation and experiment result. Whereby providing a better control strat- egy for realizing the medium frequency sinusoidal waveform inverter with high qualities of output.
