变量施肥播种机电控液压驱动控制系统设计

Design of The Velocity System of The Valve-controlled Motor on The Variable Rate Fertilizer Applicator

以89C51单片计算机为核心,控制变量施肥的电控液压驱动系统.该变量施肥电控液压驱动系统实行闭环控制,将此系统用于变量施肥播种机,实现播种机变量施肥,可有效地提高系统的动态特性和稳态特性。

Make use of the velocity system of valve-controlled motor based on 89C51 single-chip microcomputer, the variable rate fertilizer applicator for precision agriculture can be realized. Since the system make the closed-loop control, so the system can validly enhance the stability and the sensitivity of the variable rate fertilizer applicator for precision agriculture.
