Regulator problem for linear continuous-time delay systems withnonsymmetrical constrained control

The regulator problem is studied for linear continuous-time delay systems with nonsymmetrical constrained control. Necessary and sufficient conditions allowing the autors to obtain the largest nonsymmetrical polyhedral positively invariant with respect to (w.r.t.) the system in the closed loop are given, The case of symmetrical constrained control is obtained as a particular case
