　Buck-Boost转换器转换周期轨道从混乱的状态,本文提出一种　　混沌控制方法通过改善电感电流和输出电压之间的关系。通过调整　　耦合强度,这种方法可以控制混沌周期2 Buck-Boost转换器,period-4,period-8轨道　　period-9轨道和周期3,时间6,不确定不稳定周期轨道(着)。(To transform the Buck-Boost converter the chaotic state to the periodic orbits, this paper proposes a chaotic control method by improving the correlation between the inductor current and the output voltage. By adjusting the coupling strength, this method can control the chaotic Buck-Boost converter to the period-2, period-4, period-8 orbits and the period-3, period-6, period-9 orbits, without determining the unstable periodic orbits (UPOs) in advance.)

说明：  线性离散系统的批处理最小二乘参数估计的例程，噪声为方差为1的白噪声(Batch least squares linear discrete systems parameter estimation routine, the noise is white noise variance of 1)

用Viterbi algorithm筛选经过含白噪声的信息。equalizer为采用Viterbi algorithm，有效减少ISI(码间串扰)，detector为简单的检验器。对比两者的误码率。信息数量为10001bit(using Viterbi algorithm method selecting the data. compared with simple detector. data length are 10001bits. Viterbi algorithm can reduce the affect of ISI （intersymbol interference）)
