PROCESS AND DEVICE USING CONTEXT BASED EXPECTATION BY FUZZY LOGIC TO REGULATE A VARIABLE OVER AN ADMISSIBLE RANGE OF VALUES

摘要

the field of the invention is that of the regulationof physical quantities in industrial facilities.according to the invention is between two limits thethe value of a physical quantity is regulated underby changing a magnitude of disturbance. thesize of work should be reduced in amplitudeto stabilize the flow downstream and must evolve in order tothe disturbance. it is determined byusing fuzzy inference on a set of rulesdecision defined in advance, on the basis of the values of thephysical quantity is regulated, a secondary variable related tothe physical quantity is regulated, and a context variableobtained from at least one sensor or a variablecombination of variables representing the detectionphysical quantities at the origin of the disturbance of thephysical quantity is regulated. the invention finds its applicationin the processing of crude oil.the chemical pulp and paper, as well as in thefacilities and utilities, includinggas.
