％The phase locked loop(PLL),adjusts the phase of a local oscillator ％w.r.t the incoming modulated signal.In this way,the phase of the ％incoming signal is locked and the signal is demodulated.This scheme ％is used in PM and FM as well. ％We will implement it by using a closed loop system.Control systems ％techniques are applied here.

為深入了解基于UC3854A控制的PFC變換器中的動(dòng)力學(xué)特性，研究系統(tǒng)參數(shù)變化對(duì)變換器中分岔現(xiàn)象的影響，在建立Boost PFC變換器雙閉環(huán)數(shù)學(xué)模型的基礎(chǔ)上，用Matlab軟件對(duì)變換器中慢時(shí)標(biāo)分岔及混沌等不穩(wěn)定現(xiàn)象進(jìn)行了仿真。在對(duì)PFC變換器中慢時(shí)標(biāo)分岔現(xiàn)象仿真的基礎(chǔ)上，分析了系統(tǒng)參數(shù)變化對(duì)分岔點(diǎn)的影響，并進(jìn)行了仿真驗(yàn)證。仿真結(jié)果清晰地顯示了輸入整流電壓的幅值變化對(duì)系統(tǒng)分岔點(diǎn)的影響。 Abstract: In order to better understand the dynamics characteristic of power factor correction converter based on UC3854A， and make the way that parameters change influences the bifurcation phenomena of the system clearly. The math model of the two closed loop circuits to the Boost PFC （Power Factor Correction） converter controller was built. Then， with the help of Matlab， the simulation for nonlinear phenomena such as chaos and slow-scale bifurcation in the PFC converter was made. Finally the factors that have influence to the phenomenon of bifurcation under slow-scale in PFC converter were analyzed. The simulation results clearly show the parameters change influences the bifurcation point of the system.

This paper addresses the issues relating to the enforcement of robust stability when implementing the Adaptive Inverse Control (AIC) scheme. In this scheme, an adaptive FIR filter is added to a Closed-loop system in order to reduce the output error caused by external disturbances, enhancing the performance achieved by linear time-invariant controllers alone.
