文摘
- •
A modified version of LuGre friction model (LuGre-Mod) is proposed.
- •
LuGre model can only show counter-clockwise hysteretic loop, where our one, LuGre-Mod, can also exhibit clockwise behaviour.
- •
Linear analysis shows stability change via Hopf bifurcation.
- •
Linear term in LuGre-Mod model plays crucial role in system stability.
