Behaviour of extended backlash based dry friction model in Simulink in comparison with Dahl and LuGre models
is studied. Comparison with the same model but with Coulomb friction characteristic and with Dahl and LuGre models is shown. Different simulation time-step is needed for each model to reach stability when increasi...
