PARAMETER INSENSITIVE DISTURBANCE-REJECTION PROBLEM WITH STATE FEEDBACK FOR LINEAR PERIODIC DISCRETE-TIME SYSTEMS

摘要

In this paper some properties of simultaneously controlled invariance and generalized controlled invariance for linear ω-periodic discrete-time systems are investigated. Further, a necessary and sufficient condition for the parameter insensitive disturbance-rejection problem with state feedback for structured uncertain linear ω-periodic discrete-time systems to be solvable is proved.
