Original Abstract

This paper is devoted to the design of a control system applied to an industrial DVD-video drive. For high-speed players the disturbance rejection is more difficult problem than for CD players because of higher performance requirements. A combined pole placement/sensitivity function shaping methodology is used for control design purposes to reduce the effect of repetitive disturbances. Controller order reduction is performed to allow its practical implementation. Experimental results, obtained on a real system in STMicroelectronics laboratories, illustrate the performance of the proposed algorithms for both the focus and tracking control loop.
