Abstract
This paper proposes a new type of piezoactuator-driven valve system. The piezoceramic actuator bonded to both sides of a flexible beam surface makes a movement required to control the pressure at the flapper-nozzle of a pneumatic system. After establishing a dynamic model, an appropriate size of the valve system is designed and manufactured. A sliding mode controller is then formulated in order to achieve accurate tracking control of desired pressure trajectories. The controller is experimentally realized and control performances for various pressure trajectories are evaluated in the presence of the parameter variations.
