Fundamental limits in sensitivity minimization: multiple-input-multiple-output (MIMO) plants

This paper provides a bridge between the H/sub /spl infin// literature and that of fundamental limits. By applying operator theoretic tools developed for the standard frequency domain, model-matching approach to sensitivity minimization, explicit closed form expressions are given for tight bounds on the H/sub /spl infin// norm of weighted sensitivity functions for output feedback control of linear multivariable systems.
