Fixed points and controllability in delay systems
Schaefer's fixed point theorem is used to study the controllability in an infinite delay system x′(t)=G(t,xt)+(Bu)(t). A compact map or homotopy is constructed enabling us to show that if there is an a priori bound on all possible solutions of the companion control system x′(t)=λ[G...
