The Depression of High Frequency Vibration of the Ultra-Slim-Height Optical Pick-up Actuator Using the Re-Design of Modal Parameters
모달파라미터 재설계를 통한 초슬림형 광픽업 액추에이터의 고주파 진동저감
Abstract
We propose the re-design method of modal parameters to depress the 2nd resonance peak of the ultra-slim-height optical pick-up actuator. With the addition of tile counter mode near the 2nd resonance frequency, we can achieve the gain margin which is sufficient to meet the system requirement. It would alleviate the burden of the additional filter for a high-speed drive.
