This is mainly due to their power of modeling a wide ran ge of phenomena linked to modern and in-fashion technologies\, including o pinion dynamics and social networks\, machine learning algorithms for arti ficial intelligence\, big-data event-based analysis or cyber-physical syst ems\, to cite a few. Discrete-time behaviors are indeed ubiquitous nowaday s in several systems\, where the dynamics is purely intermittent or hybrid \, as characterized by the co-existence of both continuous-time (flow) and discrete-time (jump) components. In this perspective\, several methodolog ical problems arise from the applications. Most of them can be traced to t he energy and dissipation properties of complex discrete-time systems that are composed of the interconnection of elementary components through nonl inear elements. Accordingly\, a clear understanding of those properties fo r purely discrete-time systems is necessary. However\, if such understandi ng is advanced in the continuous-time framework\, the discrete-time counte rpart is still underinvestigated with a lot of unanswered questions. The o bjective of this seminar is to make a small overview on some recent result s in energy-based modeling and control of discrete-time systems with parti cular emphasis on dissipation and passivity. The classes of systems under study are those that admit a port-Hamiltonian representation. The correspo nding structures and properties\, to date\, are still unclear in the discr ete-time context despite the increasing interest.  In this sense\, a forma l characterization of the discrete-time port-Hamiltonian representations w ill be presented. Then\, on this basis\, new control methodologies are ill ustrated to solve stabilization and regulation problems for classes of dyn amical (discrete-time or digital systems). Finally\, the way these results help in formulating new discrete-time consensus algorithms for enforcing consensus on dynamical networks (involving discrete behaviors) is shown. T hose algorithms\, based on a suitable energy-based interpretation of the i nformation flow\, are shown to overcome several issues that are intrinsic to the ones that are usually employed in practice.  Short bio. Mattia Matt ioni received his Bachelor Degree (Laurea) and Master of Science (Laurea M agistrale) in Control Engineering from La Sapienza\, Università di Roma (I taly)\, both Magna cum Laude.
