| 摘 要： | 针对时间延迟对中频逆变器性能的影响,提出了一种基于状态观测器的双环控制方案,并在双环之外加入重复控制器.PI双环使系统具有快速的动态响应能力,重复控制环则提高了系统的稳态波形.最后,在一台采用DSP控制的中频逆变电源样机上得到的实验结果表明,该方案可以达到满意的稳态和动态效果.

| Abstract: | In view of the impact of time delay in medium frequence inverter,this paper introduces a dual loop control system based on state-observer.Besides,the repetitive control is added in the dual loop control system.The PI dual-loop control makes the inverter achieve fast dysnmic response,and the repetitive control loop improves the steady state performance.The control scheme is realized in the 400Hz inverter based on a TMS320LF40 DSP.The result demonstrated that this scheme could achieve good dynamic and static performances. |
