Abstract :
A time-domain solution to the problem of computing optimal values of a real block-diagonal scaling matrix in order to reduce conservatism in H2/H∞ dynamic compensator designs is presented. The optimal real block-diagonal scaling matrix is computed as a function of solutions to a Riccati and a Lyapunov equation associated with the closed-loop system. These results represent an approach to a subproblem of μ-synthesis
