Port-Hamiltonian description and analysis of the LuGre friction model
Simulation Modelling Practice and Theory, 2011 AbstractA port-Hamiltonian formulation of the LuGre friction model is presented that can be used as a building block in the physical modelling of systems with friction. Based on the dissipation structure matrix of this port-Hamiltonian LuGre model, an alternative proof can be given for the passivity conditions that are known in the literature.
