QUANTITATIVE MEASURE OF LOSS OF ADEQUACY DURING TEST MODEL FORMATION

Abstract

The main purpose of the work is to synthesize a quantitative assessment of the loss of adequacy when using non-model influence in testing systems. In the course of the research, it was found that the measure of the inadequacy of the description of the system in a classical model experiment would be calculated as a mathematical measure of the removal of the vectors of the values of the system itself and its description, that is, the measure of inadequacy of the description is a number. The use of the measure thus introduces an advantage relation into the set of permissible influences. In this case, as can be traced, the dynamic properties of the system under study, the nature of the model (unfeasible) impact, the limited purpose of the mathematical model and, finally, the limited capabilities of the test equipment are taken into account. In the general case, the search is a variation problem, in the simplest case - the study of a function for an extremum.
