Robust position control of machine tools in consideration of disturbance and variant tracking behav-ior

考虑干扰和变化跟踪行为的机床鲁棒位置控制

基本信息

项目摘要

To ensure the competitivness companies need to work more productively and therefore production machines and machine tools must fulfil increasing demands on productivity and accuracy. The machine structure can be considered as a dynamic system, which limits the achievable production speed by their damping. As remedy mechanical components with higher quality but also higher acquisition cost can be applied. On the other side controllers can be optimized to minimize the tenden-cy of vibration at higher traverse speeds. Thereby the parameters of the position controller are a compromise between productivity and accuracy, because of their influence on the damping. Aggravating a position depending behavior of feed drives consisting of ball screw drives occurs, which limits the controller parameters to be configured for the worst transfer behavior of all axis. In this project a new approach will be pursued to design a robust position controller with the background of uncertainties concerning a position dependent behavior and disturbances out of process forces.The objective of this project is the development of a method to design a robust position controller, which increases the dynamic of feed drive under the condition of equal workpiece quality. There-fore several variants of robust controllers will be analyzed and a general method to design robust position controllers will be evolved. The effectiveness of the method will be validated by experimental trials at a machine tool.
为了确保竞争力,公司需要更有效地工作,因此生产机器和机床必须满足对生产率和准确性日益增长的要求。机器结构可以看作是一个动态系统,它的阻尼限制了可实现的生产速度。作为补救措施,可以采用质量较高但购置成本较高的机械部件。另一方面,控制器可以优化,以尽量减少振动的趋势,在较高的导线速度。因此,位置控制器的参数是生产率和精度之间的折衷,因为它们对阻尼的影响。由滚珠丝杠驱动组成的进给驱动器的位置依赖行为加剧,这限制了为所有轴的最差传递行为配置控制器参数。在这个项目中,将采用一种新的方法来设计一个鲁棒位置控制器,该控制器具有与位置相关的行为和过程力干扰的不确定性背景。本课题的目标是开发一种鲁棒位置控制器的设计方法,在工件质量相等的情况下增加进给驱动的动态性。因此,本文将分析鲁棒控制器的几种变体,并提出一种设计鲁棒位置控制器的通用方法。该方法的有效性将通过机床上的实验验证。
