摘　　要：为提高400Hz中频逆变器输出的电能质量,将比例谐振控制与重复控制结合的复合控制策略应用在单相全桥电压源逆变输出波形的控制中;对复合控制理论进行分析,并给出了详细的参数设计过程。通过实验对比了比例谐振控制、重复控制、比例谐振-重复控制的复合控制策略,结果表明:复合控制策略能够有效降低400Hz中频逆变器的电压谐波含量,控制精度更高,稳态性能和动态性能良好;所设计复合控制参数合理、有效。In order to improve the output power quality of 400Hz intermediate frequency inverter,the compound control strategy of proportional resonance control and repetitive control is applied to control the output waveform of single-phase full-bridge voltage source inverter.At first,we analyzed the compound control theory and gave the detailed parameter design process.In order to prove the superior performance of the composite control,the composite control strategies of proportional resonance control,the repetitive control and the proportional resonance-repetitive control are cocmpared through experiments.The results show that the compound control strategy can effectively reduce the voltage harmonic content of 400Hz intermediate frequency inverter,and has higher control accuracy as well as steady and dynamic performance,which proves the rationality and effectiveness of the designed compound control parameter.
