| contents | This work has introduced a generalized formulation of the problem of eigenvalue spectrum assignment for block matrix systems. In this problem, it is required to construct a feedback that provides that the matrix of the closed-loop system is similar to a block companion matrix with arbitrary predetermined block matrix coefficients. Sufficient conditions for the resolvability of this problem by linear static output feedback are obtained when the coefficients of the system have a special form, namely, the state matrix is a lower block Frobenius matrix or a lower block Hessenberg matrix, and the input and output block matrix coefficients contain some zero blocks. These conditions are controllability-like rank conditions. Sufficient conditions are constructive. It is proved that, in particular cases, when the system has block scalar matrix coefficients, these conditions can be weakened. The results generalize the previous results obtained for the case of one-dimensional blocks and for the case of systems given by a linear differential equation of higher orders with a multidimensional state. Based on the main results, algorithms are developed that ensure the construction of a gain matrix. The algorithms are implemented on a modeling examples. |
