为实现高加速度高频往复旋转摆臂的高精快速定位控制，提出多种振动抑制方案。包括使用S型加减速控制以减小由摆臂惯性力造成的振动，降低摆臂转动惯量和提高摆臂联结以防止机械谐振发生，以及伺服滤波技术。在伺服滤波技术中，使用陷波滤波器抑制机械谐振，优化低通滤波器保证系统稳定性，以及使用一种新的带阻滤波器抑制中低频振动。最终实现了旋转摆臂的振动控制并达到了高精定位要求并成功应用于LED分选设备中。

Multiple vibration suppression control schemes are proposed to achieve fast and accurate positioning for high-acceleration,high-frequency reciprocal rotary arm,using S-curve acceleration/deceleration control to reduce vibration caused by inertia of the arm.Arm inertia is reduced and stiffness of coupling is raised to avoid mechanical resonance.In addition,servo filter technology is applied.In the servo filter technology,the notch filter is used to suppress mechanical resonance,the low-pass filter is optimized to guarantee system stability,and a new band-stop filter is used to suppress low and medium-frequency vibration.Finally,vibration suppression and accurate positioning of the rotary arm are achieved,successful application in the LED separation equipment is realized.
