Benzyl-cyanide reactor control system with microwave heating subsidiary control channel

For benzyl-cyanide synthesizing are exothermic reaction with risk of Heat-Centralizing accident, so it is required to control the reacting temperature and pressure steadily and accurately. This paper presents a control project of benzyl-cyanide reactor with subsidiary control channel of microwave auxiliary heating in stock warm-up. A combined-control strategy with fuzzy and delayed filter PID was used, and it can advance the stock fitting speed and warm-up equality. PXI bus hardware and Labview graphic oriented programming of the control system were discussed. App effect show that the computer control system of benzyl-cyanide reactor presented in this paper is speedy, accurate and robust in control strategy design and is logical in hardware & software collocation.
