We introduce the concept of generalized -pairs which is related to generalized -invariant subspaces and generalized -invariant subspaces for infinite-dimensional systems. As an application the parameter-insensitive disturbance-rejection problem with dynamic compensator is formulated and its solvability conditions are presented. Further, an illustrative example is also examined.
