摘要
提出广义脉冲编码调制（ＧＰＣＭ）控制和自校正加速度观测．针对气动位置伺服系统，设计出自校正加速度观测器，并成功地应用到气动位置伺服控制中．研究表明：广义脉冲编码调制控制和自校正加速度观测改善了气动位置伺服控制系统的动、静态特性，提高了定位精度．
The generalized pulse code modulation control and the self-tuning observation of acceleration are proposed in the paper.Be aimed at the pneumatic position servo system,a self-tuning acceleration observer is designed,which is applied successfully in the servo control of pneumatic position.The study shows that the generalized pulse code modulation control and the self-tuning observation of acceleration could improve the dynamic and static characteristics of the pneumatic position servo control system and could raise the positioning accuracy.
