    • A positioning control system for positioning a moving element on a basis of position command data is provided with a feedback loop. The system is also provided with a loop gain modifier for determining a loop gain, which is to be used in a following positioning operation, on a basis of a difference between an amount of overshoot measured in a current positioning operation and a predetermined tolerance or on a basis of a difference between an amount of overshoot measured in a current positioning operation and a first predetermined tolerance and a difference between an amount of undershoot measured in the current positioning operation and a second predetermined tolerance. The first and second tolerances may preferably be the same in absolute value. The moving element may specifically be a steerable mirror for drilling holes in a work by reflecting a laser beam. Also disclosed is a laser drilling machine including the system.
    • 基于位置指令数据定位移动元件的定位控制系统具有反馈回路。 该系统还设置有环路增益修正器,用于基于在当前定位操作中测量的过冲量与预定公差之间的差异或者在预定公差上基于在随后的定位操作中使用的环路增益来确定环路增益, 在当前定位操作中测量的过冲量与第一预定公差之间的差异与在当前定位操作中测量的下冲量之差与第二预定公差之间的差的基础。 第一和第二公差可以优选地具有相同的绝对值。 移动元件可以具体地是用于通过反射激光束在工件中钻孔的可操纵镜。 还公开了一种包括该系统的激光钻孔机。
