Model reference adaptive H∞ control for distributed parameter systems of hyperbolic type by finite dimensional controllers — construction with unbounded observation operator —

The problem of constructing model reference adaptive H
∞
control for distributed parameters systems of hyperbolic type is considered in this paper. The proposed control strategy is composed of finite dimensional compensators, and is derived as a solution of certain H
∞
control problem where spill-overs are regarded as external disturbance. Contrary to our previous research, we consider the case where the observation operator is unbounded in the present paper.
