摘要： 根据基因工程菌高密度发酵过程中对PH值控制的要求,采用模糊控制实现基因工程菌高密度发酵罐的PH值控制。PLC模糊控制器查表方式实现对输入量的模糊化、模糊控制表查询。给出了模糊控制算法的程序框图和部分梯形图。结果表明,用PLC实现的模糊控制器简单实用,为模糊控制技术在过程控制中的应用提供了更加广阔的前景。

Abstract: Basing on the need of PH control in process of engineering bacteria highly dense fementation,fuzzy control completes the task of the PH control of engineering bacteria highly dense fementation. PLC fuzzy controller completes the fuzziness of input signal and consulting based on fuzzy control rule by consulting table. Program frame of fuzzy control rule and some application program are given . It shows that fuzzy control with PLC is simple and practical and it provides wider application for fuzzy control technology .
