Design of Controller with Asymptotic Disturbance Attenuation

This paper formulates a generalized disturbance attenuation problem, in which two separate disturbance attenuations are required, for linear time-invariant systems having a direct transmission of controls in controlled outputs or considering disturbances in observations. We propose a design method of controllers which attain asymptotically the generalized disturbance attenuation based on the perfect regulation and the perfect observation under certain minimum phase conditions.
