On the derivation of a state-space model of a periodic process described by recurrent equations

Osvaldo Maria Grasselli, Sauro Longhi and Antonio Tornambè


Here the problem is considered of obtaining a periodic description in state-space form of a linear process which can be modelled by linear recurrent equations with periodic coefficients. A polynomial time-invariant description of such a model is used, in order to characterize the order of the model and to introduce an equivalence relation between two models.
