While these structures are unequivocally characterized in the continuous-time domain\, several descriptions are pr oposed in the literature when referring to discrete-time or sampled dynami cs. In this talk we discuss a description of port-Hamiltonian structures i n discrete time that makes reference to the notion of average passivity\, introduced to deal with systems without throughput. Exploiting the average passivity property of these forms\, we show how damping feedback and ener gy-based control strategies can be designed. Then\, we investigate the sam pled-data case and show how these forms set in discrete-time can be recove red under time-integration through modification of the interconnection and dissipation matrices characterizing the continuous-time dynamics. Some si mulations are presented to illustrate analysis and control performances\n LOCATION:https://researchseminars.org/talk/PHSeminar/9/ END:VEVENT END:VCALENDAR
