The optical disk system is widely used as a data storage system. The tracking control system of optical disk system requires a high precision and robustness against periodic disturbance and sudden disturbance. Therefore, it is difficult for only conventional feedback control system to realize the high-precision and robust tracking control system. This paper proposes high performance tracking control...
The tracking control system of next-generation optical disk system requires a high precision and robustness against periodic disturbance and sudden disturbance. The next-generation optical disk system will have the high rotational speed such as more than 10000 [rpm]. Therefore, it is difficult for only conventional feedback control system to realize the high-precision and robust tracking control system...
Airborne and space-borne imaging systems are often limited in resolution by image degradation resulting from mechanical vibrations during image exposures. A new image stabilization method using digital motion estimation and micro-mechanical compensation is presented. Motion estimation is accomplished by an auxiliary high-speed camera using modified real-time digital image stabilization (DIS) algorithm...
