Identification of models of external loads

Abstract

In the given work the problem of construction (synthesis) of mathematical model of unknown or littleknown external load (EL) on open dynamic system is considered. Such synthesis is carried out by special processing of the experimentally measured response of dynamic system (method of identification). This problem is considered in two statements: the synthesis of EL for single model and the synthesis of EL for models class for the purposes of mathematical modelling. These problems are ill-posed by their nature and so the method of Tikhonov's regularization is used for its solution. For increase of exactness of problem solution of synthesis for models class the method of choice of special mathematical models (MM) is used. The calculation of model of external load for rolling mills is executed.
