An optical servo system, which can be used in hazardous environments, is a novel and attractive control system. In our previous paper, we proposed an analytical model of a tested optical servo system which consists of an optical servo valve and a small pneumatic cylinder in order to improve the position control performance. This paper describes an extension of the optical servo system to a more normal scale system using a normal pneumatic rodless cylinder with the full stroke of 600 mm. First, two kinds of opto-pneumatic servo system using the rodless cylinder are explained briefly. Second, the control performance of the first system which uses two flow amplifiers on market is investigated. Finally, the optical servo valve is designed and improved by using the analytical model proposed previously. And the control performance of the second system using the improved valve is investigated. As a result, it is shown that the improved optical servo valve is more useful in a normal scale control system compared with the flow amplifier.
