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 the control of physical quantities in industrial facilities.according to the invention is between two limits the value of a physical quantity is regulated under perturbations by changing size.the magnitude of the amplitude must be reduced to stabilize the flow downstream and should evolve so as to avoid the interference.it is determined by a fuzzy inference on a set of decision rules defined in advance, from the values of the physical quantity is regulated.a secondary variable related to the physical quantity is regulated, and a context variable based on at least one variable or a combination of variables to detect its detectionunsuccessful of physical quantities at the origin of the perturbations of the physical quantity is regulated.the invention finds its application in the processing of crude oil, the chemical industry and the pulp and paper industry, as well as the plants and power distribution networks.in particular gas.
