摘要
由于常规PID控制器的参数往往针对一种情况进行整定,很难保持冷连轧张力始终处于一个好的控制状态。在分析了张力控制原理的基础上,应用预测函数控制设计了辊缝式调张法张力控制系统,用预测函数控制,其控制量计算方程简单,实时控制计算量小,达到了张力控制的精度要求,仿真结果证明了该控制器显著提高了系统的动态响应性能,其控制效果优于常规PID控制器。
Because of the parameter of conventional PID controller is often designed to a kind of situation and is invariable, it is difficulty to keep tension well of the tandem cold rolling mill. The tension control system by Roller gap is designed using predictive functional control on the base of analyzing the tension control theory. Using predictive functional control with fewer on-line computations can arrive to enhance the precision of the tension con- trol, the simulating result indicates that the system＇ s dynamic response performance is advanced observably, it also has more favorable characteristics than conventional PID controller.
