Abstract

In this paper, analytical study is performed to reduce residual vibration in seeking motion of optical pick-up. The conditions for acceleration and deceleration time in trapezoidal velocity profile to reduce residual vibration are derived for undamped system. To verify the validity of the conditions, two example studies are carried out. Numerical and experimental implementations for flexible arm system show that residual vibration is effectively reduced by calculated velocity profile. In addition, simulation study for optical pick-up reveals that the conditions for undamped case can be applied to obtain velocity profile with minimum residual energy in damped vibration system by changing natural frequency to resonance frequency.
