利用最佳化方法設計微小型音圈馬達控制器並應用在光學防手震系統

Abstract

OIS光學防手震的目的主要是利用鏡頭補償，改善手震造成的影像模糊現象。本論文著重在OIS控制器的設計，並提出了一個最佳化的方法能使控制器設計更為方便。論文中會介紹所選用的音圈馬達模組，以及用來當作負回授位置資訊的霍爾元件，最後是實驗結果驗證設計出來的控制器。

Optical Image Stabilization (OIS) Technology has been popular for the decade. The purpose of the OIS Technology is to compensate the lens caused by human motion to provide a clear image. This thesis primarily focuses on proposing the optimized controller method which facilities the OIS controller design. The mechanism of Voice Coil Motor (VCM) used to drive the lens and the hall sensor used to detect the vibration are introduced. Experiment results are presented to demonstrate the performance of the proposed method.
