The pneumohydraulic and the pneumatic hydraulic combination control (PHCC)

摘要

This paper puts forward a new servosystem -PHCC system - ased on the pneumohydraulic, and in the system the liguid as a control medium is led and comtrolledin closed-loop to produce variable damping force. By means of controlling the force to change the system damping ratio, the system dynamic characteristics can be improved and some special functions also be added to.
