摘　　要：阐述了广义脉码调制液压位置控制系统的组成与工作原理 ,推导了该系统的数学模型 ,并对编码规律和最小有效节流面积进行了研究。利用MATLAB仿真工具 ,对系统动态与静态响应特性进行了仿真 ,结果表明广义脉码调制液压位置控制能有效地解决The hydraulic position system with generalized pulse code modulation(GPCM) is proposed in this paper.The principle of the GPCM system is described, and its mathematical model is built up.Furthermore the coding regulation and minimum area of throttle are studied in the paper. The model is simulation is carried out by MATLAB,and the results verify that generalized pulse code modulation control system is feasible.It is also shown that using GPCM control the requirements of stability and fast response character istics for PCM system can be satisfied.
