Research output: Contribution to journalArticle


Recently high response solenoid valves have been developed capable of switching the airflow up to 200 cycles per second. If these valves are used as switching devices of the digital pneumatic pressure servo system, it enables response as quick as milliseconds for the output flow change. In this paper, the design and performance of a digital pneumatic pressure servo system using two high response valves are described. By the results of the tests on the flow characteristics and responses for output flow change, the performance of the new system is shown. The output of the servo system can yield a higher accuracy mean pressure than the conventional diaphragm-type regulator and responses within 15 millisecond. The output pressure contains ripple noise within 1 or 2% of its level. (from English abstract)
