The Coordinated Optimization Control Strategy Of Master Control Boiler System

With the continuous development of the industrial enterprises and constantlyupdate of application technology. As the source of dynamic enterprise, boiler controlsystem also experiences increasingly improvement and innovation.In this essay, theboiler master control groups is the main research object, and my task is to point outthe problem of original control scheme. In terms of the problem, I conduct researchand design for boiler control system to optimize the coordination of the parentcontrol strategy.Firstly, for the identification of data pre-boiler system, I use the waveletde-noising technology for it owns widely application prospects；By using MATLABleast squares identification toolbox to achieve recognition comparison test in order toimprove the accuracy of the system modeling, and to determine the relationshipbetween vapor pressure and the total amount of coal through the main pipe systemidentification methods; Secondly, using the three sub-systems of a single furnace asthe subject of the study to fulfill the overall design of a single furnace control scheme,and using the intelligent control technology, such as fuzzy control technology,self-optimizing control technology and so forth, complete the design for threesubsystems of single furnace steam pressure system, wind coal than self-optimizingsystem and furnace pressure system, and check them by using MATLAB simulationsoftware; Finally, basing on the deep understand of the thermal power plant boilerequipment, select "female pipe pressure boiler load following" controlstrategy,design regulator boiler line identification method, dynamic load distributionmethod and the mill load distribution method, and combine the of examples for athermal power plant boiler control group to achieve a experimental verification...
