单周控制是一种非线性控制方法。采用流图建模技术研究了单周控制开关变换器的大信号和小信号动态特性。以Cuk变换器为例，给出了单周控制系统的系统设计方法。给出了物理上的见解，解释了单周期控制如何在没有无限回路增益的情况下实现瞬时控制。实验结果表明，单周期控制的Cuk变换器在一个周期内反映了电源扰动，二极管电压的平均值在一个周期内跟随控制参考值。>
One-cycle control is a nonlinear control method. The flow-graph modeling technique is employed to study the large-signal and small-signal dynamic behavior of one-cycle controlled switching converters. Systematic design method for one-cycle control systems is provided with the Cuk converter as an example. Physical insight is given which explains how one-cycle control achieves instant control without infinite loop gain. Experimental results demonstrate that a Cuk converter with one-cycle control reflects the power source perturbation in one-cycle and the average of the diode voltage follows the control reference in one cycle. >
