中文摘要：

由于传统重复控制算法的局限性,导致在输出电压周期衔接过程所出现的输出电压跳跃现象,提出了改进的重复控制计算方法。该方法在传统的计算模型基础上增加一个过零判断控制器,用来判断重复控制的循环学习周期的起始,并以此循环直接计算重复控制的作用量,在一个周期的循环中重复控制积分和作用位置相对固定,因而有效降低了重复控制作用量的波动对输出电压的影响。最后通过对比实验结果验证了该方法的有效性。

英文摘要：

Due to the limitation of traditional repetitive control algorithm, which can cause the periodic fluctuation of output voltage,an improved method is proposed.Based on the traditional module,this calculation method adds a zero-crossing regulator to determine the start of repetitive control learning cycles, and guarantee the integral points is relatively stationary to the acting points.Finally, the experimental results verify the effectiveness and feasibility of the method.
