The robust H/sub 2/ control problem: a worst case design

Abstract

Robust stability and robust performance are investigated. The interest is in analyzing the worst-case effect of a disturbance system on the H/sub 2/ norm of a system. The corresponding synthesis question, which is to minimize the worst-case H/sub 2/ norm over the class of all robustly stabilizing dynamic controllers, is also considered. Explicit techniques to handle this problem are outlined.<>
