Numerical experiments by the method of identification of linear dynamical systems under harmonic signal

The paper presents the numerical implementation of the method of identification of linear stationary dynamic systems on the input sinusoidal signal. Identification of the system matrix is reduced to constructing and solving a matrix linear algebraic equation. The construction of the equation is based on comparison of the representation of Cauchy problem solutions in the form of exponential matrix series and results of the system phase coordinates measurement under the input sinusoidal signal. For the implementation of numerical experiments it was compiled a software in Fortran.
