Research Initiation: Dynamic Control of Direct Drives for Precision Machining Systems

这一研究启动奖为研究用于精密加工系统的直接驱动执行器的动态控制策略提供了支持。为了充分发挥直接驱动的潜力，将研究先进的动态控制技术，以解决驱动和加工过程之间的动态交互以及轴之间的动态耦合问题。目前的直线电机技术可以提供加工所需的响应、速度和力，并具有以成本优势实现更高速度和更高精度加工系统的巨大潜力。由于直线电机在机械加工中的应用很少，先进控制理论在这一问题上的应用也很少。这项研究从整个加工系统的角度研究直线电机的控制方法和技术，而不是仅仅考虑执行器，而不是独立于加工过程。

This research initiation award provides support to study the dynamic control strategy for direct drive actuators used in precision machining systems. To realize the full potential of direct actuation, advanced dynamic control techniques will be investigated to address problems of dynamic interaction between drives and machining processes and dynamic coupling between axes. Current linear motor technology may provide the response, speed and force required for machining and could have great potential to realize higher speed and higher precision machining systems at a cost advantage. Since few applications of linear motors for machining exist, advanced control theory has seldom been applied to this problem. This research investigates the control methods and techniques for linear motors from the perspective of the entire machining systems, as opposed to exclusively considering the actuator, independent of the machining process.
