Actuator and sensor selection for robust performance

Two Input Output (IO) selection methods are proposed, aimed at finding the IO sets for which a robustly performing controller exists. To avoid time-consuming p-synthesis and use X , controller existence conditions instead, the structure in the combined uncertainty/performance block is "eliminated." The first (sufficiency-based) method augments the plant by diagonal ("D-") scalings, while the second (necessity-based) method absorbs an uncertainty representation into the plant.
