摘　　要：介绍了一种压力补偿与速度反馈闭环补偿相结合的铺装机电液比例闭环速度控制系统,较好地解决了铺装机运行速度不稳定的问题。详细叙述了系统组成及工作原理,并且给出了微分改进型PID数字控制器算法.This paper introduced an electrohydraulic proportional speed closed -loop system to control the speed of spread machine, which integrated pressure compensation and speed closed -loop feedback compensation. The system has achieved good results to solve the unstable running speed of spread machine. The paper gave out the details of system components and its principle, also included the PID arithmetic controller which has been updated of differential calculus.
