Robust H-Infinity Stabilization via Parameterized Lyapunov Bounds
The parameterized Lyapunov bounding technique of Haddad and Bernstein is extended to include an H-infinity-disturbance attenuation constraint. The results presented in this paper provide a framework for designing fixed-order (i.e., full- and reduced-order) controllers that guarantee robust H-2 and H-infinity performance in the presence of structured constant real parameter variations in the state space model.
