A Simulink block diagram of the famous Lund-Grenoble (LuGre) model which captures a variety of nonlinear friction behaviours. I’ve designed the block diagram to incorporate various force inputs, so that users can explore pre-sliding hysteresis and stick-slip motion in a similar manner as the original paper [1].
Enjoy!
