Abstract :
Ortega et al. have defined a class of Hamiltonian systems such that the application of passivity-based control (PBC) yields a closed-loop energy which is equal to the difference between the stored and the supplied energies. We call this special class of PBC energy-balancing (EB). We show how EB-PBC can be extended to general nonlinear passive systems. Further we identify the physical obstacle that hampers the utilization of EB-PBC in applications other than mechanical systems. In particular, we show that EB-PBC is stymied by the presence of unbounded energy dissipation
