摘要
热轧带钢活套控制系统的优劣对轧制产品的质量与产量具有重大的影响。在实际轧制过程中,受各种因素的干扰,带钢张力并不等于液压缸的输出压力,而是存在某种非线性关系。为了研究和解决液压活套控制中的问题,本文提出了一种基于AMEsim搭建热轧带钢液压活套系统模型的方法,推导出液压缸输出压力与带钢张力之间的数学关系。通过AMEsim建立液压系统模型,由simulink建立控制系统模型,设计了专家PID控制器。联合仿真表明系统具有较强的鲁棒性。
The advantages and disadvantages of hot-rolled strip loop control system have a significant impact on the quality and yield of rolled products.In the actual rolling process,due to various factors,the strip tension is not equal to the output pressure of the hydraulic cylinder,but there is some nonlinear relationship.In order to study and solve the problems in the control of hydraulic looper,this paper proposes a method based on AMEsim to construct the hydraulic looper model of hot-rolled strip steel,and derives the mathematical relationship between the output pressure of the hydraulic cylinder and the tension of the strip.The hydraulic system model is established by AMEsim,and the control system model is established by simulink,and the expert PID controller is designed.Co-simulation shows that the system has strong robustness.
