摘要
研究如何利用Washout滤波器控制技术来控制PWM型DC/DC变换器中的混沌现象.首先分析了利用Ott-Grebogi-Yorke(OGY)方法对DC/DC变换器进行混沌控制存在的不足,然后以H啨non系统为例说明了如何利用Washout滤波器进行混沌控制.最后,应用Washout滤波器对两种采用不同控制策略的DC/DC变换器实施控制,将其从混沌状态控制到周期状态.理论分析和计算机仿真表明,该控制技术不但可以很好用于DC/DC变换器中的混沌控制,而且能够克服OGY方法的不足.
In this paper, Washout filter control technology is utilized to control chaos in pulse-width modulation (PWM) DC/DC converter. Fir stly the disadvantages of Ott-Grebogi-Yorke (OGY) method which applied to chao s control in DC/DC converter system are discussed, and then the principle of cha os control scheme with Washout filter is shown by applying the mehod to a chaoti c Hénon system. In the paper, Washout filter is applied to two kinds of PWM DC/ DC converters, which have different control schemes, and translations from chaos to period in both of the converter systems are made. Theoretical analysis and c omputer simulation show that Washout filter method can work well and overcome th e disadvantages of OGY method during controlling chaos in PWM DC/DC converters.
