| 摘 要： | 提出一种新的重复控制方案,通过电容电流内环反馈,消除逆变器固有的谐振峰,简化了重复控制器的设计;改进内模中的Q（z）,采用零相移低通滤波器,提高了系统的稳态精度。Matlab仿真结果表明,该控制方案可以获得高质量的电压输出,在非线性负载条件下THD仅为0.65%,稳态误差只有0.12%。

| Abstract: | A new repetitive control strategy is presented combined with a capacitance current inner loop,which can effectively eliminate the inherent resonant peak of the open-loop inverter so that the design of the repetitive controller is simplified.The Q(z) is also improved by using zero-phase-shift low-pass filter to further increase the steady-state precision.The Matlab simulation shows that the proposed stategy can achieve low THD(0.65%) and steady-state error(0.12%) with nonlinear loads. |
