Mixed H/sub 2//H/sub /spl infin//-controller design considering minimum entropy

In this paper an H/sub 2/ control design problem involving a constraint on H/sub /spl infin// disturbance attenuation is considered. We introduce the relation of minimum entropy/H/sub /spl infin//-controller and mixed H/sub 2//H/sub /spl infin//-controller. By the relation of the mixed H/sub 2//H/sub /spl infin// control problem and the minimum entropy/H/sub /spl infin//-control problem, we present the controller state-space realization.
