Power scaling in port-hamiltonian telemanipulation over packet switched networks

Abstract

In several important applications involving bilateral telemanipulation systems (e.g. macro-micro teleoperation, telesurgery) master and slave act at different power scales. In this contribution, we illustrate how to embed power scaling into port- Hamiltonian based telemanipulation schemes over packet switched networks. We propose a discrete scattering based communication strategy to scale the power exchanged between master and slave sides and a way to handle lost packets that allow to get power scaling while preserving a stable behavior of the system independently of any communication delay and of any possible loss of packets. © 2007 Springer-Verlag Berlin Heidelberg.
