Coupling Analysis of Slim Type Optical Pick-up using Back Electromotive Force, and Decoupling Control for It

역기전력을 이용한 슬림형 광 픽업의 연성 해석 및 비연성 제어기 설계

A novel method to measure the interaction movement, focusing direction and tracking direction in an optical pick-up, is proposed and the decoupling control for it is discussed. First, the basic principle of the coupline analysis method using back electromotive farce is introduced. Second, the interaction analysis between focusing direction and tracking direction fur commercial slim type actuator is performed using the proposed method. Finally, the coupling analysis and decoupling control for the slim type optical pick-up are discussed. From the brief simulation, we shows that the effectiveness and validity of the proposed method.
