The application and simulation of advanced process control in polymerization reactor
Abstract: With the gradual development of modern industry, in industrial production, temperature, pressure, flow rate and liquid level is the most common four process variables. Among them, the temperature is a very important process variable. For example: in the metallurgical industry, chemical industry, power industry, machinery processing and food processing and many other areas, their temperature need to be controlled like all kinds of heating furnace, heat treatment furnace, reactor and polymerization reactor . Under different production conditions and technological requirements for temperature control, heating mode, fuel, the control scheme is also different, and the ordinary PID control for polymerization reactor control system control performance is poor, so the system requires more advanced control technology and control theory, which requires such as predictive control and fuzzy control and other advanced control scheme to study the improvement method, achieve the goal of a better control performance.
Key words: PID control； fuzzy control；polymerization reactor；MATLAB
