The structured controllability radius of linear delay systems
In this article, we shall deal with the problem of calculation of the controllability radius of a delay dynamical systems of the form x'(t) = A 0 x(t) + A1x(t - h1) + ··· + Akx(t - hk) + Bu(t). By using multi-valued linear operators, we are able to derive computable formulas for the controllability radius of a controllable delay system in the case where the system's coefficient matrices are subjected to structured perturbations. Some examples are provided to illustrate the obtained results URI: http://repository.vnu.edu.vn/handle/VNU_123/27288
