逆变电源重复比例谐振控制策略

Repetitive-Proportion Resonance Control Strategy for Inverter Source

针对非线性负载和扰动引起逆变电源波形畸变的问题,提出了一种新型的逆变电源复合控制策略。控制策略结合了重复控制和比例谐振控制(PR)的优点,不但可以实现对正弦参考信号的无静差控制,而且可以有效抑制非线性负载带来的高次谐波,同时兼有良好的动态性能。最后通过仿真试验证明,重复PR控制策略具有良好的动静态性能和抗干扰能力。

For the problem of inverter source waveform distortion caused by non-linear load and disturbance, this paper proposed a new inverter composite control strategy. The strategy combines the benefits of repetitive control and proportion-resonance control. Compared with the conventional repetitive control and other control methods, the control strategy can not only achieve static error control for the sinusoidal reference signal, and also can effectively suppress high harmonies caused by non-linear load, and have good dynamic performance. Finally, the simulation experiments show that the method has good dynamic performance and anti-jamming capabilities.
