DESCRIPTION:Consider a general physical system with two power ports: how t
 o transfer energy from one port to the other? This problem is present in m
 any technological applications\, from the classical steam engine (how to c
 onvert heat into mechanical work) to motors\, generators\, fuel cells\, an
 d energy harvesting. \nCan we set up a general theory that is delineating 
 the possible limitations in energy transfer\, and guides us towards the mo
 st efficient (optimal?) control strategies?\nIn this talk I will present s
 ome partial answers (which naturally lead to further questions)\, based on
  the port-Hamiltonian formulation of physical systems. In particular\, I w
 ill show how the ‘isothermals’ and ‘adiabatics’ in the classical C
 arnot cycle for heat engines can be directly generalized to port-Hamiltoni
 an systems endowed with a specific form of internal interconnection struct
 ure (as shared by thermodynamic systems). The talk will be illustrated by 
 a series of characteristic examples\; from the gas-piston-damper system of
  thermodynamics to synchronous generators\, DC motors and electromechanica
 l actuators.\n\nReferences:\nAvdS\, D. Jeltsema\, Limits to Energy Convers
