对中厚板4300mm全液压滚切式定尺剪的电液伺服控制系统进行了详细介绍,针对伺服缸的速度和位置控制做了深入的研究,提出了自适应交互PID控制算法,对两个液压缸位置进行协同控制,试验和现场实际的运行结果表明,该控制系统可以很好的完成两路伺服缸的速度和位置控制精度要求,剪切的钢板质量达到了工艺要求。
This paper introduces the electro-hydraulic servo control system of full hydraulic rolling cut dividing shear on the 4 300 mm plate,and puts forward the adaptive interaction PID control algorithm to control the position of two hydraulic cylinder in a cooperative way through in-depth researches on the speed and position of the servo cylinder. Both experiments and actual operations show that this control system could control the speed and position of two servo cylinders precisely and make the quality of steel plate sheared keep in line with the technical require-ments.
