电压模式控制Buck变换器中的混沌吸引子重构技术

利用Buck变换器的输出电压时间序列可以进行变换器的混沌吸引子重构，其中延迟量可以通过时间序列的自相关函数来确定，而重构维数也可根据混沌吸引子的关联维来确定，仿真和特征参数计算均表明Buck变换器的重构混沌吸引子与原混沌吸引子拓扑等价，具有相同的动力学性质和几何性质，另外，构建了一个延迟重构实验电路，得到的实验波形也验证了上述结果。

Reconstruction of Chaotic Attractor in Voltage-mode Controlled Buck Converter

The chaotic attractor of voltage-mode controlled Buck converter can be reconstructed through time series of output voltage. In this way, the time delag will be determined by autocorrelation function, and reconstruction dimension will be determined according to correlation dimension of chaotic attractor. Simulation and numerical calculation of characteristic parameter show that the reconstruction result equals to the original chaotic attractor topologically. Furthermore, an experimental plant is built to prove the former results.
