H-INFINITY GUARANTEED COST CONTROL FOR UNCERTAIN CONTINUOUS-TIME LINEAR-SYSTEMS
Systems & Control Letters. Elsevier Science Bv, v. 20, n. 6, n. 413, n. 418, 1993.
This paper deals with the H(infinity) guaranteed cost control problem for continuous-time uncertain systems. It consists of the determination of a stabilizing state feedback gain which imposes on all possible closed-loop models an H(infinity)-norm upper bound gamma > 0. Assuming that the uncertain domain is convex-bounded and the uncertain system is quadratic-stabilizable with gamma disturbance attenuation, it is shown how to determine, by means of a convex programming problem, the global minimum of gamma. As a particular and important case, for precisely known linear systems, the last problem reduces to the classical H(infinity) optimal control problem. The results follow from the definition of a special parameter space on which the above-mentioned problems are convex.206413418
