Identification of dynamic models of space constructions according to actual test data

A new approach to analytic model parameter adjustment according to the data obtained by the system of current construction state measurement during its operation is proposed. This approach contains the stage of the determination of modal model parameters on the basis of identification of the model output with measured state-output when construction is being operated, and the stage when the adjustment of the obtained computing model parameters are carried out on the basis of acquired data on the frequency spectrum and data of analytic model, used as deficient information. High definition correction of the analytical model is performed from the DCC of the corrections wwhich pull together the model and the real construction dynamic behaviors. Use of this method allows to provide the requirements for spacecraft dynamic model development and investigation accuracy.
