Abstract

This paper presents a new type of an optical pick-up for CD- RIM drive feeding system. The optical pick-up is activated by a pair of bimorph piezoceramic actuators in order to achieve fine motion control of the objective lens. Following the derivation of the governing equation of motion, a control model, which takes into account the hysteresis behavior of the actuator and also parameter variation such as frequency changes, is established in a state space form. A robust controller is then formulated and experimentally realized. Various position trajectories to be followed by the optical pick-up are adopted and tracking control responses are presented in time domain. In addition, control durability is demonstrated in order to provide a practical feasibility.
