该项目旨在研究鲁棒性 反馈控制基于对干扰的估计， 切削力、低速摩擦补偿和前馈 基于机器进给驱动系统的逆动力学的控制， 以及这些控制方案与标准计算机的集成 实验室人员的数控（CNC）功能 电脑 加工中心将被用作试验台， 演示控制方案及其集成。 由此产生的系统将是一个原型交钥匙系统， 使机床开发人员、程序员和 运营商将获得先进控制的全部好处， 具有机床动力学和控制理论的专业知识。 预计这一项目将产生重大影响， 高速加工的高度竞争领域。

The projects seeks to investigate the combined use of robust feedback control based on estimation of disturbances such as cutting forces, low-velocity friction compensation, and feedforward control based on inverse dynamics of machine feed drive systems, and the integration of these control schemes with standard Computer Numerical Control (CNC) functions on a laboratory personal computer. A machining center will be used as a test bed for demonstrating the control schemes and their integration. The resulting system will be a prototype turnkey system, which makes it possible for machine tool developers, programmers and operators to receive the full benefit of advanced controls without specialized knowledge of machine tool dynamics and control theory. It is expected that this project will have a significant impact in the highly competitive area of high-speed machining.
