THE UNILATERAL QUADRATIC MATRIX EQUATION AND PROBLEM OF UPDATING OF PARAMETERS OF MODEL

The algorithm of construction of solutions of the unilateral quadratic matrix equation in case of complex eigenvalues of the corresponding matrix pencil is offered. As application, the problem of updating parameters of model by experimentally estimation of eigenvalues of this system is considered. Efficiency of the offered procedure of updating is shown on the example of system with two degree of freedoms.
