Abstract
In this paper, a dead-zone non-linear control strategy is developed and implemented in an optical drive (CD-RW) to improve anti-shock performance during playing and recording. An experimental platform has been realized to evaluate the shock resistance of the drives using a real-time interface system. This user-friendly platform not only provides an easy and flexible way for the evaluation of the non-linear controller but also allows a quick implementation and evaluation of new control algorithms for Optical Disc Drives. Experimental investigation on the CDRW drive shows that the dead-zone non-linear controller can improve the anti-shock performance by about 60%.
