A more robust servo control system using Sliding Mode Control to handle shock and vibration disturbances for optical disc drive systems is presented in the paper. An estimator-based SMC controller is used in the radial servo-loop instead of the traditional PID controller. Simulation and experimental results show a significant improvement of the drive?s anti-shock performance in the radial direction. The same algorithm can be applied to the focus servo-loop.
