    A design method of controllers which ensure internal stability and attain asymptotically H disturbance attenuation is presented. The design procedure consists of two steps: (1) to design an H state feedback control via an algebraic Riccati equation approach; and (2) under a certain minimum-phase condition, to recover the achievable performance asymptotically by applying high-gain observers. It makes use of the perfect observation for the design of high-gain observers. It is shown that the asymptotic recovery can be attained by using reduced-order observers, provided there is no direct feedthrough of controls and disturbances in observations.
