本文就抗生素发酵生产过程,提出了一种补料时机的Fuzzy识别、预报的建模方法,并根据20m~3发酵罐工业数据的分析,选取了以总糖、总糖变化率、氨基氮和氨基氮变化率四个主要参数作为输入集因素,运用本文提出的方法,建立了一个实际的抗生素发酵生产过程补料时机的 Fuzzy 识别、预报模型。经现场调试效果良好,与富有经验的行家相比,准确率达90%以上。 Based on the analysis of 20m ~ 3 fermentor industrial data, this paper chose the total sugar, the rate of change of total sugar, amino nitrogen and Amino nitrogen rate of change as the main factor of the input set of four factors, using the method proposed in this paper, the establishment of an actual fermentation process of antibiotics feeding time fuzzy recognition and forecasting model. The field debugging effect is good, compared with experienced experts, the accuracy rate of 90%.
