摘要: 該文使用參數(shù)微擾方法控制電流控制模式Boost變換器在連續(xù)電流模式下產(chǎn)生的混沌行為。文中利用離散模型確定了系統(tǒng)運(yùn)行的混沌區(qū)域,并在設(shè)計(jì)控制環(huán)時(shí)作了適當(dāng)?shù)暮?jiǎn)化,以利于實(shí)現(xiàn)。仿真分析和實(shí)驗(yàn)都顯示,這一方法對(duì)于開(kāi)關(guān)電路是有效的。電路的穩(wěn)定被重新建立,并在此基礎(chǔ)上進(jìn)一步擴(kuò)大了變換器的工作范圍,文中還分析了噪聲在控制中的影響。

Abstract: OGY method(1990) is applied to control the chaos exhibited by current-mode controlled boost dc-dc converter, as its chaotic regime has been established in this paper. This is achieved by using discrete-time model and making simplification of the control loop design. Both simulation and experiment are done. Stability of the circuit is obtained, which proves this control method is valid in controlling switching circuit. -
