Abstract: The friction torque and motor ripple torque are main factors that influence the position tracking accuracy of high precise servo turntable control system. Against the influence of friction torque and motor ripple torque on the system, the paper presents an integrate disturbance torques compensation strategy. First, it proposed a PD feedforward control method with the friction observer, which compensated dynamic friction torque in the system, and it analyzed the system's stability depending on Lyapunov stability theory. Furthermore, combining with the disturbance observer based on the repetitive learning control, it proposed an integrate disturbance torques compensation strategy. On one hand, the proposed method may compensate the friction in the system. On the other hand, the inductive repetitive controller may restrain well the periodic ripple torque and the disturbance observer is used to compensate the uncertainty that is aroused by repetitive control and friction compensation to the system. The simulation results prove the effectiveness of the proposed method.
