Representations and structural properties of periodic systems (2007)
Aleixo, J.C., Polderman, J.W., Rocha, P.
We consider periodic behavioral systems as introduced in [Kuijper, M., & Willems, J. C. (1997). A behavioral framework for periodically time-varying systems. In Proceedings of the 36th conference on...
A contribution to the study of periodic systems in the behavioral approach (2007)
Aleixo, J.C., Polderman, J.W., Rocha, P.
In this paper we obtain new results on periodic kernel representations and propose a definition of “image" representation for periodic behaviors. Further, we characterize controllability and...
Controllability, autonomicity and free variables in periodic behaviors (2006)
Aleixo, J.C., Polderman, J.W., Rocha, P.
In this paper we propose a new type of “image” representation for periodic behaviors and analyze the relationship between image representability and controllability, showing that the...
