早在五十年代,国外曾发表过有关气动伺服的论文,并成功地把PI 调节运用到高温(1000℃)高压(150bar)的气动位置控制系统中。此后的二十多年里,气动伺服的研究停留在理论和实验阶段。其原因之一是空气压缩性大、粘度小,用普遍的古典方法和模拟调节器,很难达到理想的精度要求。近几年来,由于现代控制技术和微型计算机的发展,为这个问题的解决提供新的可能性。1979年西德Aachen R.W 工业大学W.Backe 教授领导的液压气压传动及控制研究所成功地研制出第一个气动伺服阀,大大推进了这一领域的研究,相继不少大学研究所、公司把气动伺服研究列入重点项目,每
As early as the fifties, foreign papers on pneumatic servo were published and successfully applied to the pneumatic position control system of high temperature (1000 ℃) and high pressure (150bar). The next twenty years, the research of pneumatic servo stayed in the theoretical and experimental stages. One of the reasons is the air compressibility, small viscosity, with the classical methods and simulation of the general regulator, it is difficult to achieve the desired accuracy requirements. In recent years, due to the development of modern control technology and microcomputers, new possibilities for solving this problem have been provided. In 1979, West Germany Aachen RW Industrial University Professor W.Backe hydraulic pressure transmission and control of the Institute successfully developed the first pneumatic servo valve, greatly promoted the research in this area, many universities have research institutes, the company Pneumatic servo research included in the key projects, each
