✦ Synopsis

The structural properties of linear periodic discrete-time systems are analyzed in the periodic polynomial representation. It is shown that the classical polynomial approach for linear time-invariant systems can be extended to periodic systems. New deÿnitions and properties are given in terms of skew polynomial rings and periodic di erence algebra. Necessary and su cient conditions for the characterization of reachability, controllability, observability and reconstructibility are given in this framework.

The disturbance lc,calization problem for left invertible linear periodic discrete-time systems is solved using periodic state feedback contrc,llers. The proposed technique is of algebraic nature and has the following two main characteristics: (i) It yields simple al~ebraic criteria for testing the
