摘要
介绍了一种适用于高性能中频SPWM逆变电源的重复PD(比例微分)控制方案。该方案运用到一台采用TI公司TMS320F240DSP的400Hz、5.5kW的逆变器上,重复控制器能够获得足够的稳定性和谐波抑制能力。同时,PD控制可以改善系统的动态性能。实验结果表明该方案可以得到稳态时较小的谐波畸变和突变负载时的快速响应。
This paper introduces a Repetitive PD (Proportion and Differential coefficient) Control method for high performance SPWM medium-frequency inverter. And this method is used in the 400 Hz and 5.5 kW inverter based on TMS320F240 DSP. Repetitive controller can obtain enough stability and satisfactory harmonic rejection. And at the same time, the PD controller can improve system dynamic performance. Experimental results prove that this method can achieve not only low harmonic aberrance during steady-state operation but also good transient response subject to load step change.
