Abstract

In this paper we present a generic Port-Hamiltonian (PH) model that includes cable dynamics (in particular elasticity and couplings with the platform and all cables among each other) of a cable-driven parallel robot (CDPR), which is used as a motion simulator. Moreover we consider changes in the cable parameters, i.e. it's elasticity, mass and length when the cables are wound/unwound from the winches. To the best of our knowledge nobody considered such a detailed and generic model of a CDPR in PH structure before. Since motion simulators are built to mimic systems with different physical properties, PH modeling can pave the way for physics-shaping controllers.
