While these structures are unequivocally charac terized in the continuous-time domain\, several descriptions are proposed in the literature when referring to discrete-time or sampled dynamics. In this talk we discuss a description of port-Hamiltonian structures in discr ete time that makes reference to the notion of average passivity\, introdu ced to deal with systems without throughput. Exploiting the average passiv ity property of these forms\, we show how damping feedback and energy-base d control strategies can be designed. Then\, we investigate the sampled-da ta case and show how these forms set in discrete-time can be recovered und er time-integration through modification of the interconnection and dissip ation matrices characterizing the continuous-time dynamics. Some simulatio ns are presented to illustrate analysis and control performances.\n LOCATION:https://researchseminars.org/talk/PHSeminar/6/ END:VEVENT END:VCALENDAR
