Abstract: A new kind of pneumatic position control system is proposed. The system mainly consists of a miniature air compressor, an ON/OFF solenoid valve and a cylinder. The position of the cylinder can be controlled by directly driving the miniature air compressor. The structure, working principle and experimental characteristics of the developed compressor are described. The validity of this system is confirmed through experiments.
