对提高ＳＰＷＭ逆变电源输出电压波形质量的重复控制技术作了深入研究。重复控制技术能减小周期性波动负载（如整流负载）引起的输出电压波形畸变。在已往基本重复控制和无过冲重复控制的基础上，提出了一种预测重复控制算法，以解决重复控制算法中的参数优化问题。仿真结果表明，将预测重复控制与瞬时值反馈控制结合起来构成的新型控制系统对ＳＰＷＭ逆变电源输出电压波形的周期性畸变有很强的抑制作用。
To improve the SPWM inverter output voltage waveform quality of repetitive control technology made in-depth study. The repetitive control technique can reduce the waveform distortion of the output voltage caused by the periodic fluctuating load (such as rectifier load). Based on the former basic repetitive control and the non-overshoot repetitive control, a predictive repetitive control algorithm is proposed to solve the parameter optimization problem in the repetitive control algorithm. The simulation results show that the new control system which combines the predictive repetitive control with the instantaneous feedback control has a strong effect on the periodic distortion of the output voltage waveform of the SPWM inverter.
