  • The unilateral quadratic matrix equation and problem of updating of parameters of model
    V.B. Larin (pp. 202-209)
  • Abstract

    The algorithm of construction of solutions of the unilateral quadratic matrix equa- tion in case of complex eigenvalues of the corresponding matrix pencil is o®ered. As application, the problem of updating parameters of model by experimentally estimation of eigenvalues of this system is considered. E±ciency of the o®ered procedure of updating is shown on the example of system with two degree of freedoms.

    Keywords

    unilateral quadratic matrix equation, matrix sign function, parameters updating.
