摘　　要：针对板带热连轧机传统活套高度控制策略存在的问题,提出用模糊自适应整定P ID的控制策略.控制器输入取活套量的偏差e和偏差变化率ec,输出取P ID控制器3个参数的修正量,从而实现了P ID参数的在线自整定.通过M ATLAB语言,进行了传统P ID控制与模糊自适应整定P ID控制动态性能的仿真比较,结果表明采用模糊自适应整定P ID控制可明显提高活套高度控制系统的动态性能.The fuzzy self-adaptive PID control strategy is used to replace the traditional loopers height control method on hot strip tandem mill. The inputs required by the control model are loopers＇ height error and the error change rate. The model gives the correct additional setpoint for the three parameters of PID control individually. Thus the on-line automatic adjustment of the PID parameters is achieved. The fuzzy adaptive PID control is compared with traditional PID by simulation through MATLAB. The results show that the loopers＇ height dynamic control performs much better by using the fuzzy adaptive PID control strategy.
