While these structures are unequivocally characterized in the continuous-time domain\, several descri ptions are proposed in the literature when referring to discrete-time or s ampled dynamics. In this talk we discuss a description of port-Hamiltonian structures in discrete time that makes reference to the notion of average passivity\, introduced to deal with systems without throughput. Exploitin g the average passivity property of these forms\, we show how damping feed back and energy-based control strategies can be designed. Then\, we invest igate the sampled-data case and show how these forms set in discrete-time can be recovered under time-integration through modification of the interc onnection and dissipation matrices characterizing the continuous-time dyna mics. Some simulations are presented to illustrate analysis and control pe rformances\n LOCATION:https://researchseminars.org/talk/PHSeminar/9/ END:VEVENT END:VCALENDAR
