Abstract

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^-2_opt of the Riccati equation. First the correspondence between γ^-2_opt and the first order eigenvalue of a Hamiltonian difference system is presented,and then the computation procedure based on this corresp...

Key words: discrete H∞ control, Hamiltonian difference system, Riccati equation, eigenvalue
