摘要
根据发酵动力学规律建立了柠檬酸发酵过程中的菌体增殖、基质消耗及产物积累的数学模型，并从碳平衡导出了间接测量模型。系统模型参数用广义最小二乘法进行估计。用推广卡尔曼滤波迭代算法进行状态实时估计取得令人满意的结果。
itricacid fermentntion process was studied in this paper.According to principle of the fer-mentation process kinetics,the mathematical models of biomass proliferation, medium consumption and citricacid production were given for the citric acid fermentation process。 The calculation formula for mycelium con-centration was derived indirectly from carbon balance,The parameters of the mathematical model were esti-mated by the GLS.The model curves from computer simulation were verified by the results of experiments.Satisfactory results were achieved by using the extended Kalman filtering iterative algorithm for on-line state estimation.
