| 摘 要： | 为解决用户侧微电网单相逆变器系统输出电压的谐频问题,考虑采用双反馈控制策略来进行系统控制器设计。针对在非线性负荷条件下采用PID控制器进行用户侧微电网单相逆变器控制,不能取得满意的谐频抑制问题,提出采用电压外环路伺服系统鲁棒性控制和电流内环路滑模控制相结合的控制设计。仿真结果表明,在不同负荷条件下用户侧光伏微电网单相逆变器系统输出电压总谐波失真低,瞬态响应快和渐近跟踪基准输出电压好,谐频效应减到最小。

| Abstract: | In order to solve the harmonic frequency problem of the user side micro-grid single-phase inverter system output voltage, it is considered using the double feedback control strategy to design the controller. The combined control design of outer voltage loop servo system robustness control and inner current loop sliding mode control is proposed to solve the problem of the satisfied harmonic frequency suppression can't be got that the user side micro-grid single-phase inverter system uses the PID control strategy, under different load conditions make total harmonic distortion of the user side micro-grid single-phase inverter system output voltage is small, fast transient response, good asymptotically tracking the reference output voltage, harmonic frequency effect being reduced to the minimum.. |
