Admissibility of retarded diagonal systems with one-dimensional input space

Rafal Kapica, Jonathan R. Partington, Radoslaw Zawiski

We investigate infinite-time admissibility of a control operator $B$ in a Hilbert space state-delayed dynamical system setting of the form $\dot{z}(t)=Az(t)+A_{1}z(t-\tau )+Bu(t)$, wher…
