Abstract :
Investigates in a unified framework two basic feedback optimization problems, rejection of output disturbances in the presence of plant uncertainty, and contraction of radius of uncertainty for MIMO plants. Duality theory is provided showing existence of optimal feedback laws. Optimal and nearly optimal solutions are characterized, and flatness conditions are derived. The theory developed allows previous convex programming based numerical methods to be applied to this class of problems
