摘要
该文研究如何利用OGY混沌控制技术来消除DC/DC变换器的混沌状态。首先利用数据采样方法得到系统的离散模型,利用计算机技术由该离散模型进行可以得到系统的分叉图,从分叉图中可以看到DC/DC变换器发生了混沌、分叉等非线性现象,然后从理论上说明了如何利用OGY混沌控制策略把工作在混沌状态的DC/DC变换器控制到周期状态,最后利用计算机对DC/DC变换器进行仿真研究,仿真结果证明了该文中基于OGY方法DC/DC变换器混沌控制策略的有效性。
To control chaos in PWM DC/DC converter OGY technology is applied in this paper. Firstly, the discrete mode of DC/DC converter is produced based on sample - data method. And the bifurcation chart can be made by iterating the discrete mode using a computer. Nonlinear phenomena, such as bifurcation and chaos, can been seen in the bifurcation chart. And then the principle how to control a chaotic DC/DC converter to periodic condition is illustrated, and the computer simulation shows the validity of chaos control scheme based on OGY technology.
