摘要: 针对常规气压伺服系统的缺点,基于传统的气液联动技术,将液体介质引入到气压伺服系统中并进行闭环控制,从而构成了一种全新的气、液复合介质传动系统——气液联控伺服系统。它借助于液体可变阻尼力的调整来改变系统的动态特性,并实现一些特殊的机能。试验证明了气液联控伺服系统实现了常规气压伺服系统难以达到的高刚度、高精度和高频响,对气压技术应用领域的拓宽具有重要的理论和实际意义。

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.
