比例节流控制的流量数字压力补偿（特性校正）研究

Investigation into digital pressure-compensation (characteristic correction) of flow in propor tional resticted control

本文提出了一种运用数字控制和压力传感技术对比例方向（节流）阀进行数字压力补偿的方法。理论分析和实验均表明，采用该方法可比采用传统机械式补偿方法有更好的静、动态控制特性，且算法执行时间短，实时性好。

This paper puts forward a methodof digital pressure-compensation in proportionaldirectional (restricted) valve by using numeri cal control and pressure sensing technique. Theoretical analysis and experimental result showthat this method has better static and dynamiccontrol characteristics than the traditional method of mechanical compensation, and has shortalgorithm execution time.
