摘要
针对一类典型生化反应乙醇连续发酵过程，在实验验证模型的基础上，运用数值方法研究了连续发酵系统中出现的混沌行为。固定外加激励幅值，通过改变激励频率可以明显看出由单一周期解经由倍周期道路通往混沌的演化过程。结果表明，当激励频率ω＞０．２５８ｈ－１时系统出现混沌，随着ω的进一步增大，出现多种周期窗口。
For a kind of typical biochemical reaction ethanol continuous fermentation, numerical methods are used to study the chaotic behavior of continuous fermentation based on the model testified by the experiments. Fixing the amplitude and changing the frequency of forced simulation, we find an evolution procedure of the system through period doubling route to chaos. The results show that the chaos will appear when ω>0.258h -1 and there will be many periodic windows with the increasing of ω.
