| 摘 要： | 单周控制的开关变换器有较强的输入扰动抑制能力,但是负载扰动抑制能力较差。本文建立了单周控制系统在不连续导电(DCM)模式下的连续时间模型,在此基础上设计PID控制器,得到带输出反馈的单周-PID闭环控制系统。整个系统具有较强的输入扰动抑制能力和负载扰动抑制能力,并有良好的动态、稳态性能。

| Abstract: | The switching converter based on one-cycle controller can reject input disturbance very well, but it has poor capability for rejection of load disturbance. In this paper, a model called continuous time model is established in discontinuous conduction mode （DCM）, and a PID controller is designed..4 closed loop control system combining one-cycle and PID controller with output feedback is established. The overall system shows high capability for rejection of input disturbance and load disturbance, and its steady-state performances and dynamic ones are quite well. |
