应用模糊推理控制面包酵母补料分批培养中的乙醇和葡萄糖浓度。该模糊控制器由3个隶属函数（溶解氧（DO），乙醇和葡萄糖的浓度）和18个产生式规则。模糊推理由IF {A是a且B是B，. x 007 D;，则{C是c}从在线测量的DO、乙醇和葡萄糖的浓度。当面包酵母补料分批培养中乙醇和葡萄糖的“培养基”浓度分别为2g/l和0.2g/l时，乙醇和葡萄糖的浓度分别控制在2.67± 0.35g/l和0.27± 0.25g/l，乙醇产量从26 g/l降低到34 g/l，与0.2g/l的仅葡萄糖对照相比，细胞产量分别从0.38 g干细胞/g消耗的葡萄糖增加到0.53 g干细胞/g消耗的葡萄糖，乙醇产量从0.50 g乙醇/g消耗的葡萄糖降低到0.14 g乙醇/g消耗的葡萄糖。
Fuzzy reasoning was applied to control both ethanol and glucose concentrations in fed-batch cultures of baker's yeast. This fuzzy controller consisted of three membership functions (concentrations of dissolved oxygen (DO), ethanol and glucose) and 18 production rules. Fuzzy inference was carried out by IF {A is a and B is b,...#x007D;, THEN {C is c} from the on-line measured concentrations of DO, ethanol and glucose. When “medium” concentrations of ethanol and glucose in fed-batch culture of baker's yeast were set at 2 g/l and 0.2 g/l, both ethanol and glucose concentrations were controlled at 2.67±0.35 g/l and 0.27±0.25 g/l, respectively, ethanol production was reduced from 26 g/l to 34 g/l, cell yield increased from 0.38 to 0.53 g dry cell/g consumed glucose and ethanol yield decreased from 0.50 to 0.14 g ethanol/g consumed glucose, respectively, as compared with those of the glucose only control at 0.2 g/l.
