Grey Theory And Its Application Of Automatic Coagulation Dosing System Forecasting Of Water Works

Grey theory is a rising subject, grey control theory is a new control theory, and it has strong adaptability. Grey system gives emphasis to investigate the issues that have little sample, poor information and can't be solved by statistics or fuzzy mathematics. According to the overlay of the information, the practical orderliness through the sequence-building has been found. It doesn't need the accurate model; its point is modeling based on few numbers. The nucleus of grey system theory and method is the dynamic model of grey, and his characteristic is coming or bring into being function and grey differential equation.The dynamic model of grey is coming or bring into being the function concept with the grey serving as the foundation, and with the differential drawing up closing the pattern the building method for the nucleus, to build pattern thought is directly changing the time alignment to the differential equation grey system, thus builds that the development abstracting the system changes the dynamic model, and namely Grey's Dynamic's Model, in brief note is for GM.The paper started with grey system theory.A few conceptions of the grey system,grey relational analysis and grey modeling process have been discussed in detail,and modeling method proposed of grey correlation analysis and forecasting model of grey system combining gray prediction model. Program was gicen to validate these above models.Then the weakening the introduction of the system operator of the gray prediction model has been set up to the data of production statements of Wuhan Zongguan Water Works (2008.6-10) by matlab using practical data of the forecasting model.The result shows that the algorithm is effective in the industrial process.This thesis introduces the related theory of water treatment project, application of grey system theory in coagulation dosing system forecasting of water works, and combination of artificial intelligence and artificial neural network model, coagulation dosing system optimize the system of more specific, and has prove the application value in coagulation dosing system forecasting of grey theory, advanced another method and ideas in coagulation dosing system of water works.
