• Adaptive control
• Friction compensation
• IP position control
• Parameter identification
• Permanent magnet linear synchronous motor
• Robustness

Such factors as nonlinear friction force and mover mass variety can affect the precision of permanent magnet linear synchronous motor (PMLSM) servo system. The model reference adaptive system based on Coulomb friction was designed to compensate the friction on-line. The IP controller was designed to satisfy the dynamic performance of system position. The designed model reference adaptive parameter identifier was combined with the adaptive friction compensation system. The mover mass was identified by the parameter identifier to update the mover mass in the model reference adaptive control system based on the Coulomb friction. The simulation results indicate that the proposed method can improve the position tracking precision and increase the robustness of the system.
