Research in the Design of the Fuzzy Controller Intelligence of the Measuring and Controlling Apparatus on Water-Content in Material Pulp

Abstract:

In the course of producing material pulp, water-content (or the density of material pulp) is a very important process parameter. There are many elements which affect the water-content of material pulp, therefore it is very difficult to build precise mathematical module. In the meantime, the control system is nonlinear and retarded. For such control systems, the classical control system and modern control system is always hard to be applied, but fuzzy control can usually gain good results. This paper briefly illustrates the basic composing frame graph of the fuzzy control system of the automatic measuring and controlling apparatus on water-content in material pulp. We design the fuzzy controller of the automatic measuring and controlling apparatus on water-content in material pulp from these aspects: from the fuzzification of the sendout values, the rules of fuzzy reasoning, the adjustment of fuzzy control rules through the principle of double-factor self-organized fuzzy control, and the précising of the input values, and etc., and give the program frame graph of the fuzzy control algorithm. The successful application of the Intelligence Measuring and Controlling Apparatus on water-content proves that the design of the fuzzy controller is reasonable.
