摘　　要：在研制烧碱蒸发微机控制系统时 ,对烧碱浓度模糊检测中的隶属函数进行了研讨 ,并对生产现场采集的数据进行分析和验证 ,模糊检测控制器所涉及的偏差、偏差变化率、输出控制量的模糊集均符合正态分布 .实际应用证明 :隶属函数设计的模糊检测控制器 ,对烧碱浓度的测量具有较高的精度 。In the development of the microcomputer control system for caustic-soda evaporation, it makes the discussion for membership function of caustic-soda concentration fuzzy measurement. Through the analysis of the data which were collected in the production site and the experiments: the deviation the deviation change rate, the fuzzy set of output control amount concerning the fuzzy mesaurement controllers conform to the normal distribution. The application of the fuzzy measurement controller with the normal function as the membership function proves that the measurement process of the caustic-soda concentration has higher accuracy. The determination of membership function provide a valuable reference to the development of the microcomputer fuzzy control technology.
