The Research Of The Intelligence Controlling System In Beer's Fermentation Process

Aiming at the controlling to production of beer with usual equipment in many beer factories of our country, there're many disadvantages in such production process The data of product can't be protected and analyses, controlling accuracy and mobility can't satisfy and easily produce the problem of the qualityc It adopts IPC - PLC distributed control system, the function of the system is very higl reliability and practically techniques advancement completely meets the demand of modern production, furthermore, improves the demand of developmentThe thesis mainly improves BP neural networks fuzzy controlling self-adaptive controlling arithmetic , according to characteristics of inertia and time lag in beer's fermentation process.. First, It applies fuzzy logical in the abstract and non-linear dealing ability; second, it applies neural net in the self-study and any functions approaching ability ?Through combining above two ability, it can find a best P I D non-linear controlling regularity and achieve controlling on line of the unknown subject etCo Therefore, it not only can strengthen robust and intelligence of the system, but also make design simple and easily be requiredoIn addition, the thesis also does many works on procedure of upper-computer and basic-controller and the whole system designed can be put into work immediately...
