A New Architecture of Computer Numerical Control Servo- Controllers

该奖项旨在为机床开发一种新的伺服控制器结构，该结构结合了可变增益交叉耦合和实时调节表观轴向转动惯量的方法。这两种方法分别被证明可以改善轮廓加工中的插补误差。将这些方法结合起来，并将其扩展到多轴轮廓加工中，是本研究的合理和必要的延伸，可以在正常和高速的轮廓加工中实现更高的精度。通过与计算机数控系统制造商的密切合作，这项研究工作将对国内工业基地具有重要意义，同时也将推动伺服控制系统在制造业中的应用。

This award is to develop a new servo controller architecture for machine tools incorporating the methodologies of variable gain cross-coupling and real time adjustment of apparent axial moment of inertia. These two approaches have been independently demonstrated to improve interpolation errors in contour machining. The combining of these methodologies and extending them to multi- axes contouring is a logical and necessary extension of this research, to achieve higher accuracies while contour machining at normal and high speeds. This research effort, in close collaboration with manufacturers of Computer Numerical Control systems, will be of significance to the domestic industrial base while advancing the state-of-art in servo controlled systems applied to manufacturing.
