基于FPGA的活套高度和张力系统解耦控制器设计

Decoupling controller design of a looper height and tension system based on FPGA

    摘要
  • 摘要: 针对板带热连轧机活套的高度和张力系统,在工作点附近,以实际热轧现场数据为依据,建立了对象的动态数学模型。采用基于BP神经网络整定的PID控制策略以减弱系统的耦合影响,并给出了其控制算法在FPGA上实现的方法,包括脉动阵列算法映射、数据表示及精度和运算部件设计。仿真结果验证了本算法的有效性和控制策略的适用性。

     

    Abstract: The dynamic mathematic model of a looper height and tension system was built on field data for hot strip finishing mills. A control strategy based on BP-PID was introduced to decouple the looper system by using FPGA, which includeds systolic mapping, data representation and precision, and computation components design. Simulated results showed the effectiveness of the algorithm and the applicability of the control strategy.
