摘　　要：分析定量阀结构和控制原理,将传统的恒频脉冲控制算法与梯形曲线算法、S形曲线算法进行了对比,选择用拟合S形曲线的算法控制定量阀。同时,为了有充足加减速过程,使用细分驱动技术,在不增加控制器硬件成本前提下,通过拟合7段S形曲线,最终实现了高精度定量阀的精密定位控制。This paper analyzed the structure and control principle of quantitative valve. After comparing the traditional constant frequency pulse control algorithm, with the trapezoidal curve algorithm, and S curve algorithm, fitting S curve algorithm was close to control the quantitative valve. At the same time, in order to have enough acceleration and deceleration process, the subdivided driving technology was applied, by fitting 7 segments S curve and without increasing hardware cost was realiged, the precision positioning control of high-precision quantitative valve was realized.
