Identification of Disturbed Stabilization Systems based on Experimental Data

The paper deals with the structural identification of complex dynamic systems. The identification experiment is described. The algorithm of the structural identification based on the analysis of experimental data is represented. The possibility of solving the identification problem with random controllable and uncontrollable disturbances is shown. The proposed identification problem is solved by the example of the aviation stabilization system. Graphical dependences of theoretical and experimental spectral densities of system outputs are represented.
