Abstract:
To counter
the defects of the normal pneumatic servo system, a new kind of compound
medium transmission of gas and liquid – the pneumatic hydraulic
combination control (PHCC) system is put forward, which is based on the
traditional pneumo-hydraulic system and the liquid medium is led into
the pneumatic servo system and controlled in close-loop. In this system,
the dynamic characteristics are changed by means of regulating the
damping force of the liquid and some special functions are realized. The
conclusion is that the PHCC servo system can realize high rigidity, high
precision and high frequency response, which the normal pneumatic servo
system is difficult to perform. It is significant of developing the
pneumatic technique.
