摘　　要：瓦楞纸在生产轧制过程中需保持原纸张力的恒定,原有的各种生产线因用人工调节张力而影响了生产率和产品质量,为此研制了一种新型的张力测控系统。张力检测环节中引用了卡尔曼滤波法对被噪声污染的张力信号进行准确估测;研究了张力控制系统的数学模型,结果证明:该系统是时变线性系统,据此采用模糊自整定PID控制策略对原纸张力进行了恒张力控制,达到了较理想效果。几年来的推广应用证明了该系统的实用性和可靠性。It is necessary to keep constant tensile force for the raw material paper in tegular cardboard production line.The productivity and product quality was poor,however,because the tensile force was controlled by manual work at foretime.A new tensile force examine and control system was developed therefore,in the system,the tensile force was estimated or measured accurately with Kalman filter.The mathematic model of the control system was studied,and according to it,got the tensile force be constant with selfregulating fuzzy PID policy.
