| Research Abstract |
In this study, a twin-drive geared system which connected two servomotors with a gear train to realize speeding-up operation at the feeding axis of the presswork machine was taken up and a vibration suppression control for energy-saving in operation was developed. As an energy-saving vibration suppression control technique, a model-based control was developed. The effectiveness of the model-based control is verified by using the test stand which imitates the feeding axis of the presswork machine. The higher-order vibration related to the backlash was suppressed. Further, the settling time of the residual vibration of 26Hz was shortened down to about 1/3 of the uncompensated vibration level.
