Abstract: The existence of a discrete H full-information controller depends on the existence of solutions of the associated Riccati equation. Therefore, the existence condition of the controller can be determined by calculating the critical value γ-2opt of the Riccati equation. First the correspondence between γ-2opt and the first order eigenvalue of a Hamiltonian difference system is presented,and then the computation procedure based on this corresp...
