Abstract :
The paper discussed an adaptive friction compensation scheme based on Coulomb friction and a parameter identifier. The model reference adaptive system based on Coulomb friction was designed to compensate the friction on-line. The designed model reference adaptive parameter identifier was combined with the adaptive friction compensation system and the mover mass was identified by the parameter identifier to update mover mass in the model reference adaptive control system based on Coulomb friction. Simulation results show that the position tracking precision of system and robustness were improved.
