FAST RESPONSE PNEUMATIC SERVOSYSTEMS WITH DIGITAL VALVES

抄録

The use of digital modulating valves for the development of pneumatic servosystems is becoming a widely employed technique. The main requirement for the valves is low response time, and typically it involves the size to be relatively small. The paper deals about the possibility to use small, fast response valves coupled with larger, and slower, valves inorder to obtain fast response and wide bandwidth in large size servosystems. The faster valves provide the system with the capability to obtain high precision, while the larger valves allow high flows in order to increase the fastness of the system.
