| 中文摘要 |
| 在带钢连续退火机组中, 张紧辊区域的带钢张力直接影响着机组的运行速度以及带钢质量, 因此, 张紧辊区域的带钢张力是连续退火机组中的关键被控变量. 本文首先建立了张紧辊区域带钢张力的动态机理模型和状态空间模型, 并针对张紧辊带钢张力系统的多变量、强耦合等特性, 采用极点配置和动态解耦算法, 提出了带钢张力的多变量解耦控制器. 仿真实验结果表明, 所提出的解耦控制器实现了多个带钢张力控制回路之间的动态解耦, 并可获得良好的控制效果. |
| 英文摘要 |
| In the strip continuous annealing line, strip tension of the bridling roll is an important factor that can affect the strip quality and the operation speed of the continuous annealing line. The strip tension of the bridling roll is the key controlled variable in the control system of the continuous annealing line. The dynamical mechanism model and the state space model of the strip tension in the bridling roll are proposed. According to the multivariable coupling characteristic of the strip tension, a decoupling controller of the strip tension is also presented, which is the ntegration of the pole assignment and multivariable dynamical decoupling method. Simulation experiment results show that the proposed decoupling controller can realize the dynamical decoupling of the multiple strip tension control loops, and the satisfactory control performance also can be achieved. |
