The “Closed-loop Control System of Catalytic Cracking Gasoline Pressure” researched and developed by Institute of Computer Applications of Changling Refining and Chemical Plant passed the technical appraisal organized by the Development Department of Petrochemical Corporation on April 18, 1996. The system consists of online gasoline vapor Pressure Analyzer (by Changling Petrochemical Plant Computer Institute of Applied Research) and industrial control computer. The system uses advanced predictive control technology, the use of system identification methods, the establishment of predictive control model. The software adopts the module structure, and the design of the drawing screen is applicable, intuitive and finished. The operation interface adopts the menu mode. Easy to set and modify control parameters. In order to display the curve of the adaptive recording range, it provides convenient analysis of field data. At the same time some of the important parameters of the right to modify encryption to prevent misuse and irrelevant personnel changes affect the control, guarantee
