Abstract
In this paper, the finite-time state observer design problem for a pneumatic servo system is investigated. In the case of without velocity sensors, a velocity observer is developed. Through rigorous stability analysis, it is proved that the designed observer is locally finite-time convergent. Based on the proposed observer, an output feedback linearization controller is proposed for position tracking control of the pneumatic servo system. Numerical simulations illustrate the effectiveness of the proposed velocity observer.
