|Title:||H∞ Guaranteed Cost Control For Uncertain Continuous-time Linear Systems|
|Abstract:||This paper deals with the H∞ guaranteed cost control problems for continuous-time uncertain systems. It consist of the determination of a stabilizing state feedback gain which imposes on all possible closed-loop models an H∞ -norm upper bound γ > 0. Assuming that the uncertain domain is convex-bounded and the uncertain system is quadratic-stabilizable with γ disturbance attenuation, it is shown how to determine, by means of a convex programming problem, the global minimum of γ. As a particular and important case, for precisely known linear systems, the last problem reduces to the classical H∞ optimal control problem. The results follow from the definition of a special parameter space on which the above-mentioned problems are convex. © 1993.|
