9412733曹这项研究的目标是研究机械加工过程的动态建模和实时控制，特别是钻削。该项目将使用混合时间域和钻角域对钻削过程进行建模，使用统计时间序列正则变量分析技术识别多输入多输出时变的非线性过程参数，并将稳健的自适应反馈和前馈算法用于成形刀具钻削和高速钻削过程控制。此外，该项目还将研究如何使用主轴和进给驱动功率或电流来代替钻削扭矩和推力，作为工厂实施成本效益的反馈措施。该项目的成功实施有可能显著提高钻井质量，扩大作业制度。它还可以为其他加工过程的动态建模和过程控制提供一种方法学。

9412733 Tsao The objective of this research is to investigate the dynamic modeling and real-time control of machining processes, in particular drilling. This project will use mixed time domain and drill angle domain modeling for the drilling process, statistical time series canonical variate analysis techniques for identifying the multi-input and multi-output time-varying nonlinear process parameters, and robust adaptive feedback and feedforward algorithms for form tool drilling and high-speed drilling process control. In addition, this project will investigate the use of spindle and feed drive power or current in lieu of the drilling torque and thrust force as feedback measurements for cost effective factory implementation. The successful implementation of the project has the potential to significantly improve drilling quality and extend operating regimes. It could also provide a methodology for dynamic modeling and process control of other machining processes.
