The Application And Research Of Distributed Computer Control System Based On JX-300XP

The SUPCON JX-300 XP DCS system is the representative of new species which the Zhejiang University Zhongkong Technique Limited Company manufactures, a new distributed control system based on the field bus. This topic combines this system with various control objects of laboratory, and sets up a DCS control platform according to practice. On this basis completed many kinds of controls plan and many design task, including the control configuration, the plan flow chart, the trend curve, the data report form, the reports to the configuration; Finally integration the laboratory actual controlled object, some of the convention control experiment has been done to part of control plan, with the experimental result and the experimental curve is obtained ,and analysis has carried on to each kind of experimental result, achieving better control results.Although DCS is the computer control system most widely used nowadays, the DCS of most business enterprises still stays around the routine control, so as to the development of its resources has the important meaning. Among them, the research of the advanced control is a very important part.In actual production process, the coupled and complicated control system that has the big delay and multivariate generally very rarely arrives its precise mathematics model then can't be carried out valid control. Now the routine PID control scheme is adopted, attaining no favorable effects. Along with the development of the modern control theories and over year practice, the technique of advanced control protocol is already mature, especially in view of the modern industry which can't establish the accurate mathematics model .Aimed at these features of complex processing, this text makes use of MATLAB to carry out simulation study on part of the fuzzy control algorithms, then develops fuzzy control algorithms using the SCX language of the SUPCON system combined with the actual controlled object in the laboratory and in view of the control procedure in industry. The real-time control is achieved by the algorithms. The effect of experiment demonstrates that the whole control system has the good stability, robust and noise immunity.
