    摘要:

    超精密运动台作为半导体设备的核心部件,其伺服精度与主动抑振能力直接决定了半导体设备的性能.针对超精密运动台高速运动时,测量基准因动力学特性受到机器内部噪声的激励而产生振动,导致超精密运动台在这些模态下跟随误差变大的问题,本文研究了一种基于加速度计前馈控制的主动抑振方法,利用加速度计对被测对象加速度信号实时采集的特性精准测量谐振频点,使用相位延迟滤波器解决信号延迟,并通过设计前馈控制器对振动信号进行有效衰减.以实验室设备为例,通过MATLAB等软件进行数据处理与仿真验证,以及整机性能验证,确认基于加速度计前馈控制的主动抑振方法对解决高频振动引起伺服误差较差的有效性、可靠性与可行性.

    Abstract:

    As the core component of semiconductor equipment, the servo accuracy and active vibration suppression capability of ultra precision motion table directly determine the performance of semiconductor equipment. In response to the problem of vibration caused by the excitation of internal noise due to the dynamic characteristics of the measuring benchmark during high-speed motion of the ultra precision motion table, which leads to an increase in tracking error of the ultra precision motion table in these modes. This article studies an active vibration suppression method based on accelerometer feedforward control. The resonant frequency point is accurately measured using the characteristic of real-time acquisition of acceleration signals of the measured object by the accelerometer. The signal delay is solved by using a phase delay filter, and the vibration signal is effectively attenuated by designing a feedforward controller. Taking laboratory equipment as an example, data processing and simulation verification were carried out using software such as MATLAB, as well as overall performance verification, to confirm the effectiveness, reliability, and feasibility of the active vibration suppression method based on accelerometer feedforward control in solving the problem of poor servo error caused by high-frequency vibration.
