Quadrant glitches are often observed on the circular trajectories of NC machine tools. In this study, a friction compensator that can compensate for the friction characteristics in a microscopic region is proposed. In the compensator, friction forces and torques are modeled using a simple mathematical model, and the estimated friction torque around the motor axis is added to the torque command. In order to evaluate the effectiveness of the proposed friction compensator, the compensator was… CONTINUE READING
