| Abstract | Pneumatic actuators are widely used not only in term of their force transfer but also in term of position control. Generally, the difficulty in controlling the precise position exists in a pneumatic system because of its nonlinearity and uncertainty of compressed air. The objective of this research is to develop a robust controller for a servo pneumatic system in order to control the movement of the piston to any target position. The personal computer was used as the controller and communicated with sensing unit via ISA interface card. The optimal model of the servo pneumatic plant was presented and utilized in the implementation of the Disturbance observer based control (DOB). Two loops, internal and external loop, of the observer design were required. The main concept of the internal loop was to force the input-output character of this inner loop to approximate the nominal plant model and the external loop was designed for approaching the system requirement. In this research, the PID controller was applied in this external loop |
