摘　　要：针对张力控制系统的时变性和耦合性,通过卷辊和带材的动力学分析,建立了张力系统动力学模型,分析了影响张力的主要因素。为解决常规PID控制在张力控制过程中难以实现参数整定的问题,提出CMAC与常规PID并行控制方案,利用CMAC的非线性映射能力适应时变系统的要求。建立了控制系统模型,并进行了仿真。结果表明,该方法的控制效果优于常规PID,抑制扰动能力强、稳定性较好。Considering time variability and coupling of tension control system, a mathematical model of tension was established based on tbe dynamic analysis of unwinding roll, winding roll and strip, and the primary factors influencing tension change were analyzed. A parallel control project combining CMAC and traditional PID control was put forward to solve the difficulty of defining the parameter in tension control process by using routine PID. The nonlinear mapping ability of CMAC was used to fit time variability of tension system. To analyze the system performances, the system model was established, and simulation was carried out. The results showed that the control performance based on CMAC is superior to traditional PID control; the system has a well stability and disturbance attenuation.
