Abstract

Abstract: Based on the nonlinear bifurcation theory, a continuous calculation method that delineates the location and stability of all equilibuium states, both steady and time-dependent, is developed. As a demonstration, we further analyze behaviors of opened-loop and closed-loop systems in which S. cerevisiae is continuously cultured. With bifurcation studies of the solution branches in state global stability of the set-point are derived.

摘要： 本文利用连续性算法在揭示啤酒酵母连续培养过程开环特性的基础上证实了五组分模型具有比传统双组分模型更好的可信性,并根据非线性的分枝理论进一步揭示了系统经闭环控制后存在的多定态、极限环以及浑沌等现象,为控制增益的合理选取提供了依据.
