Generalized (C, A, B)-pairs for linear periodic discrete-time systems

In this paper the concept of generalized (C/spl gamma/(/spl middot/), A/sub /spl alpha//(/spl middot/), B/sub /spl beta//(/spl middot/))-pairs for linear uncertain /spl omega/-periodic discrete-time systems is introduced and its properties are investigated. Further, the parameter insensitive disturbance-rejection problems with dynamic compensator for uncertain linear /spl omega/-periodic discrete-time systems is formulated and its solvability conditions are presented.
