In this paper the problem of the asymptotic tracking and stabilization with infinite gain margin, is addressed for linear time-invariant discrete-time multivariable systems in the case when unknown different scalar gains act on the outputs. Necessary and sufficient conditions for the solvability of the problem by means of a linear periodic discrete-time error feedback dynamic controller are derived. A procedure is given for designing the proposed periodic controller (containing an internal model of the reference signals).

Abstract
In this paper the problem of the asymptotic tracking and stabilization with infinite gain margin, is addressed for linear time-invariant discrete-time multivariable systems in the case when unknown different scalar gains act on the outputs. Necessary and sufficient conditions for the solvability of the problem by means of a linear periodic discrete-time error feedback dynamic controller are derived. A procedure is given for designing the proposed periodic controller (containing an internal model of the reference signals).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
