| Abstract: | Because nonlinear friction affect greatly servo System, friction compensation based on LuGre model is bring forward. State z is adopted observer to estimate which is not measured. Self-adaptive law brought forward can compensate greatly low speed affect that friction act in servo system, and method of Lyapunov is proved that the self-adaptive control law can make system stability and expectant signal can be gradually traced. Finally matlab is used to simulate system, and this mothed is proved to be valid. |
