【摘要】 针对强非线性发酵体系的振荡、多稳态特性以及相位行为特性,提出了一种综合考虑过程的稳定性及相位行为特性进行操作区域划分的策略,并将所提策略对厌氧型发酵体系操作区域进行区域划分。通过对各个子区域进行综合分析,可以分析出过程的稳定性、相位行为特性随操作条件变化而变化的情况,进而为发酵过程的稳定操作和设计改进提供科学依据。更多还原

【Abstract】 Many nonlinear fermentation system exhibit oscillation behavior、multi steady-state characteristic and nonminimum phase behavior. Here a strategy of segregating the operating regimes into distinct zones is proposed on the basis of stability/instability and minimum/nonminimum phase. Also we applied this strategy to analyze the anaerobic fermentation system. Through the analysis of distinct zones respectively, it is clear that how the inherent properties (stability and controllability) of a process change with its operating conditions, which provides scientific foundation for improving process design and keeping stable operation.更多还原
