广义脉冲编码调制（ＧＰＣＭ）控制是针对脉冲编码调制（ＰＣＭ）控制气动系统中控制精度与控制范围、稳定性与快速性之间的矛盾而提出的。本文建立了ＧＰＣＭ控制气动伺服系统的数学模型，并进行了详细的仿真和实验研究，结果证明了该方法的有效性
Generalized pulse code modulation (GPCM) control is aiming at the contradiction between control accuracy, control range, stability and fastness of pulse code modulation (PCM) control pneumatic system. In this paper, a mathematical model of GPCM pneumatic servo system is established, and a detailed simulation and experimental study is carried out. The results show that the method is effective
