Estimator-based sliding mode control of an optical disc drive under shock and vibration

A more robust servo control system using sliding mode control (SMC) 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 experi...

Description
Summary:A more robust servo control system using sliding mode control (SMC) 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.
