Based On The Matlab Real-time Control Research And Intelligent Boiler Control System

The paper mainly designs a control system to control water level and temperature of boiler. It can measure several parameters of boiler on-line, such as temperature, water level, pressure, flux, value position and motor frequency and so on.The platform of experiment is process control equipment called "EFPT-1-01" model made by a componey in ShangHai. The control system uses different algorithm to control different object type of the equipment. For example, improved PID algorithm is used in water level control, and fuzzy algorithm is used in temperature control. The debug result indicates that the control scheme is effective. Otherwise the paper also gives emulational process of the decoupling control of temperature and water level, and the simulation result illustrates that a feed-forward decoupling controller can clear the coupling of systems.The software of control system uses the programming tool of C++ Builder 6, and complex control algorithm such as fuzzy control is compiled by Matlab, so that programming with C++ Builder and Matlab can come true. The finished control system includes the real-time data acquisition, the real-time curve plotting, the field operate guiding and the process controlling. The friendly user interface uses Chinese language, and it is very easy to operate.Finally, it is shown by the experiment that the designed control system has the advantages of high reliability and short periods and good applicability.
