Abstract


MSG is commonly used as a condiment in human life. Currently, the technological level of domestic production of MSG mainly rely on the experience of the operator of the production process, production control, but with the MSG production process became more complex, more and more mass continuity, the temperature of the fermentation process, PH value dissolved oxygen concentration required online measurement and control, and these parameters are highly nonlinear, time-varying and large lag, making the fermentation process control becomes more complex. MSG production process is divided into sugar, fermentation, extraction and purification of the four stages of the process, in which the the glutamate fermentation is the most important aspect of, control the temperature in the fermentation process, pH control, dissolved oxygen control and eliminate bubble control need to understand the requirements of the control of various parameters. Control requirements and the need to control and execution point more to enhance the distributed control system (DCS) the control centralized control and management, not only can greatly improve the level of automation, also can make the products in the production process quality, yield and economy are improved. The paper uses the Siemens SIMATIC PCS7 control system design, operation and management platform, the entire production process of MSG. The system consists of the automation station, engineer station and operator station bisects level integration, automated station the underlying field implementing agencies connection according to process requirements, program design, engineer station, operator station remote monitoring and control of the upper, the entire system from the bottom to the top, orderly distribution and overall integration. This article focuses on the design and implementation based on fuzzy adaptive PID controller. In view of traditional PID can not meet the requirements of the complex parameter control, but has the advantages of simple algorithm, strong adaptability, robustness, fuzzy control, intelligent control technology does not require a precise mathematical model, wide applicability, but the algorithm is more complex, to combine both of them to each other to form a fuzzy adaptive PID controller can be used to meet the requirements. This article was designed and fuzzy adaptive PID controller for MSG production process control, the first parameter simulation study using Matlab / Simulink parameters fuzzy control query table; then using the language of the SCL SIMATIC PCS7 control system platform (PCS7 Function Block Development Language) programming, develop a fuzzy adaptive PID function block, used in PCS7 procedures development; Finally SIMATIC PLCSIM simulation software simulation, comparing the fuzzy adaptive PID block with the traditional PID block control performance. This fuzzy adaptive PID function block has been applied to the actual production process, single-loop test results show that the function blocks to achieve good control effect.
