Motion Error Compensation

Servo systems of NC machine tools must minimize trajectory control tracking error by preventing machine resonance and trajectory error between forward and backward paths by improving symmetry. To address such issues, we propose two-degree-of-freedom control using a reference model and a servo control method with the mechanical-characteristics-compensator to compensate for machine vibration. Results of experiments confirmed the effectiveness of our proposed control.
