Adaptive Vibration Control for System with Friction Damping

摘要：

The dynamic model of the single-degree-of-freedom (SDOF) mass-spring system with friction is established, based on the Lugre friction model. An observer-based model reference adaptive controller (MRAC) is proposed. By Lyapunov method, it is proved that the closed-loop system is asymptotically stable and the displacement as well as the velocity tracking errors can converge to zeros. Simulation work is carried out in both frequency and time domain. The results show that the proposed controller can greatly attenuate the response of the system significantly for both harmonic and random excitations.
