TWINSCAM is a camera system that synthesizes the two images shot with two cameras above the surface of the water and below the surface of the water at the side of the swim pool. And it achieved a new effect of the images in live TV programs of synchronized swimming.

This paper proposes a new high speed robust tracking control system based on both “Zero Phase Error Tracking” (ZPET) control system and robust servo system for an optical disk recording system. In the optical disk recording systems (for example CD-R), the tracking servo system must have the complete tracking response whose error is less than 0.1 [μm] for an amplitude of 100 [μm] of reference input signal. However, its detecting signal is only a tracking error. For this purpose, this paper proposes a new estimation method of the reference input signal by using only tracking error, and realizes the high speed robust tracking servo system with ZPET control. Moreover, this paper considers the saturation of controller output. The experimental and simulation results point out that the proposed system has a quick and precise tracking response.
