| 摘 要： | 基于内模原理的重复控制技术在逆变电源的波形控制中应用相当广泛,它对死区、非线性负载引起的波形畸变有很好的抑制作用。提出一种新的重复控制方案,通过改进周期信号发生器中的Q(z),在重复控制器的给定处插入延时环节z-m以及采用母线电压解耦,在很大程度上提高了系统的稳态精度。仿真和实验证实,使用该控制方案的逆变电源在带波峰因子为3的非线性负载时,输出电压THD控制在0.6%,很大程度上提高了逆变电源的稳态性能。

| Abstract: | The repetitive control scheme based on internal model is widely used in inverters.It has good performance of reducing voltage distortion caused by nonlinear loads and dead time.A new repetitive control scheme,which includes improving Q(z),inserting a lag part z-m and decoupling of bus voltage,is presented to further reduce the steady-state error.The method is verified by simulations and experiments and it achieves low THD(0.6%) with nonlinear loads. |
