Arbitrary matrix coefficient assignment for block matrix bilinear control systems in the Frobenius form

The paper relates to the classical problem of eigenvalue spectrum assignment. We consider this problem in a generalized formulation. The system coefficients are block matrices. It is required to construct a controller that assigns the given block matrix coefficients of the characteristic matrix polynomial to the closed-loop system. For block matrix bilinear control systems, we obtain sufficient conditions for resolving the problem of arbitrary matrix coefficient assignment for the characteristic matrix polynomial when the coefficients of the system have a special form, namely, the state matrix is a lower block Frobenius matrix, and the matrix coefficients at the controller contain some zero blocks. It is proved that, the main result generalizes the corresponding theorem for block matrix linear control system closed-loop by linear static output feedback. It is shown that sufficient conditions are not necessary. Special cases are considered. Examples are presented to illustrate the results.
