METHOD FOR IDENTIFICATION OF THERMAL PARAMETERS OF DISTRIBUTED OBJECT OF GIVEN SHAPE Russian patent published in 2007 - IPC G05D23/22 

FIELD: technology for controlling temperature of objects with clearly shown spatial distribution.

SUBSTANCE: temperature is measured for object with cyclic functioning in each cycle in points, evenly distributed across whole volume of object and from cycle to cycle. Whole general set of data is divided on classes of organizational-technological situations. Measurement errors resulting from doubtful measurement results are screened. Field being inspected is modeled in each class of organizational-technological situations. Whole set of measurement results in each class of organizational-technological situations is divided on two parts: training selections and control selections. Modeling errors are found in all selections. Model is adjusted using training selections separately for each class of organizational-technological situations. Full dispersions of measurement results and inadequacy dispersions are calculated from control selections independently from each class of organizational-technological situations. Homogeneousness of aforementioned dispersions is checked. Classes of organizational-technological situations are grouped so that in each groups full dispersions and inadequacy dispersions are homogeneous. Controlling and controlled excitation effects, and also edge conditions, are related to identification signs of organizational-technological situations and to classification of experimental and modeling data. Model adequacy check is performed separately for each group of classes of organizational-technological situations in accordance to typical procedure developed for point objects with usage of Fisher's F-criterion.

EFFECT: decreased duration of experiment.
