Transfer-function models for a new class of physically-realizable inverse-systems for linear dynamical systems

The author previously (1994) presented a new alternative formulation of, and solution to, the inverse-system realization problem, based on “disturbance-observer” techniques of disturbance-accommodating control theory (DAC). In the present paper that inverse-system realization methodology is used to develop explicit, physically-realizable, guaranteed stable transfer-function models for generic families of inverse-systems S^-1 corresponding to families of given (linear, time-invariant) systems S described also by transfer-function models
