介绍了一种脉冲非线性控制技术——单周期控制。该技术利用开关变换器的脉冲和非线性特性，实现对斩波电压或电流平均值的瞬时控制。该技术提供快速的动态响应和良好的输入扰动抑制。它适用于脉宽调制 (PWM) 转换器和准谐振转换器的控制。单周期控制理论是在分析具有传统反馈控制和电流模式控制的基本降压转换器的基础上发展起来的。通过实验验证了降压变换器单周期控制的可行性。研究了单周期控制开关变换器的动态行为。以Cuk转换器为例进行分析和实验。一周期控制理论被推广到控制所有类型的开关转换器：恒定频率、恒定导通时间、恒定关断时间和可变开关。>
A pulsed nonlinear control technique, one-cycle control, is introduced. This technique takes advantage of the pulsed and nonlinear nature of switching converters and achieves instantaneous control of the average value of the chopped voltage or current. This technique provides fast dynamic response and good input-perturbation rejection. It is suitable for the control of pulsewidth-modulated (PWM) converters and quasi-resonant converters. The one-cycle control theory is developed based on the analysis of the basic buck converter with conventional feedback control and current-mode control. Experiments were conducted to verify the feasibility of one-cycle control of the buck converter. The dynamic behavior of one-cycle controlled switching converters is studied. The Cuk converter is used as an example for the analysis and experiments. The one-cycle control theory is generalized to control all types of switching converters: constant frequency, constant turn-on time, constant turn-off time, and variable switches.>
