摘要
提出了一种PWM占空比控制换向阀阀芯位置的方法,通过PID调节器调节PWM占空比实现了换向阀对液压油缸的高精度速度和位置控制,从而在飞剪控制系统中取代伺服比例阀对飞剪剪刃进行速度和位置的运动控制,有效减少了设备维护成本。
This paper presents a PWM control method to control valve spool position. By PID regulator regulating PWM duty cycle to achieve high accuracy on the hydraulic cylinder speed and position control, so that directional valve can replace servo proportional valve to control flying shear for blade speed and position in the flying shear control system, which can reduce equipment maintenance costs availably.
