Abstract


The boiler in the industry have extensive application of boiler system with nonlinear and strong coupling, multivariable and unstable characteristics. Pressure control have been rich new subject, so this paper research the boiler pressure control. For boiler system modeling and difficult to control to the characteristics, so this paper developed based on real-time control platform to RTW boiler system is controlled.RTW is the MATLAB graphical modeling and simulation environment is an important complement of Simulink function modules , It is a based on Simulink code automatic generation of environment . It can directly from the model of optimizing simulink.this produced, portable and personalized code, and according to the target allocation automatically generate various environment program.This paper introduces the RTWT placing type (MATLAB RTW) and double model (XPC) two target system structure, through the analysis and comparison, chose to use RTWT, and in RTWT goals compiled data acquisition and control card PCI - 16MFP and MATLAB interface, thus establishing the program software platform, for boiler control system flexible use of this experimental platform provides a way, and it has certain popular value.Secondly, in order to accurately control boiler pressure, this paper also for real-time control platform designed the pulse signal, finally the conventional PID control and fuzzy control to large inertia, big lag, nonlinear boiler control system pressure and real-time control. Detailed introduction of the two control algorithm of controlling principle and specific control object design two controller, which has verified the feasibility of this scheme, from the side shows the feasibility of the experiment platform. In addition, this paper also built hardware platform. The experimental platform for us with different methods, obtain the best repeatedly testing the control method and control parameters, to strengthen our innovation capacity provides effective way. The experimental platform, with further optimization software and hardware technology development, the experimental platform to promote a certain role in promoting laboratory construction.
