电液伺服阀的控制是数控弯管机控制系统中的关键;通过利用增量式PID控制方法,采用工业控制计算机、计数器/定时器及数模转换器,实现了对电液伺服阀的准确控制。在实际应用中弯管质量和重复精度高,完全能够满足生产要求。
The control of electro-hydraulic servo valve is the key to the control system of CNC pipe bender. By using incremental PID control method, using industrial control computer, counter / timer and digital-analog converter, control. In practice, the pipe bending quality and high repeat accuracy, fully able to meet production requirements.
