摘　　要：生物反应器控制系统决定了生物反应的速度和代谢产物的质量,当前生物反应器控制系统在温度、酸碱度、溶解氧浓度等参数的控制上,存在可靠性低、实时性不强等问题,使得微生物无法在最佳的环境下生长,对目的产物的合成也有直接的影响。本文分析了目前主流的几种控制系统的优势和不足,嵌入式控制系统设计比较灵活,能够满足个性化的需求,但运算能力低;可编程逻辑控制系统一般用于工业控制,但功能的局限性比较大;工业控制计算机系统运算能力比较强,但成本相对较高。最后展望了生物反应罐控制系统的发展趋势,提出智能化的控制系统。The bioreactor control system determines the rate of biological reaction and the quality of metabolites.The current bioreactor control system has problems such as low reliability and low real-time performance in the control of temperature,pH,dissolved oxygen concentration and other parameters,making it impossible for microorganisms to grow in the best environment and directly affecting the synthesis of target products.This article analyzes the advantages and disadvantages of the current mainstream control systems.Microprogrammed control is more flexible in design and can meet individual needs,but has low computing power.Programmable logic control system is generally used in industrial control,but its function is limited.Industrial control computer system has strong computing capacity,but relatively high cost.Finally,the development trend of the bioreactor control system is prospected,and an intelligent control system is proposed.
