Intelligentized Control And Realization Of Ball Mill Pulverize System Burthen

The boiler pulverizing system adopt mainly steel ball milling coal machine and mill storage pulverizing system , because the system has characteristics , such as , strong coupling , great time lag and slow time change . The quantity of storage coal in the ball milling coal machine can't measure exactly. Manpower operation or use conventional regulate intrument can't get often perfect control effect . Generally there are some problems such as consume energy highly and autocontrol difficultly. Therefore , adopt fuzzy control theory and research the control run of the mill storage pulverizing system in this paper, which has an important engineering practicality value.In this paper , after analyzed many effect factors of the mill storage pulverizing system in the 200MW unit in GUIYANG power plant, researched the burthen change charateristic of the pulverizing system. Applied fuzzy control rule including many variables input and many variables output and set up the subject function including three input variables which affects pulverizing system. Devised fuzzy controller and constituted fuzzy decision-making using fuzzy control rule. This fuzzy control system applied LIKONG庐 control system in GUIYANG power plants , the system's fuzzy control and the plant's primary control system are accordant. It makes the run state of the power plants into more secure , steady and economic.Dispense with modeling adopting fuzzy control system and adapt to the control and design of non-linearity system . Perform fleetly and expediently and the cost of exploitage is low. Especially, the ball mill storage pulverizing system can run sostenuto at optimal state. It's applied foreground is amplitude and inaugurate a new approach for the design of thermodynamic automatic control system...
