The Depression of High Frequency Vibration of the Ultra-Slim-Height Optical Pick-up Actuator Using the Re-Design of Modal Parameters
초록
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.
