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。
單週控製的開關變換器有較彊的輸入擾動抑製能力,但是負載擾動抑製能力較差。本文建立瞭單週控製繫統在不連續導電(DCM)模式下的連續時間模型,在此基礎上設計PID控製器,得到帶輸齣反饋的單週.PID閉環控製繫統。整箇繫統具有較彊的輸入擾動抑製能力和負載擾動抑製能力,併有良好的動態、穩態性能。

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.
