离散负载扰动观测器在高速线材连轧机中的应用

Application of Discrete Load Disturbance Observer in High Speed Wire Rod Continuous Rolling Mill

  • 摘要: 为了抑制高速线材连轧机直流调速系统未知外扰(负载力矩)对系统造成的不利影响,设计了离散负载扰动观测器及带前馈扰动补偿的直流调速系统,并将重构的负载扰动应用于微张力控制.现场实验表明,所设计的系统有效地改善了调速系统的动、静态性能,改善了微张力控制效果,提高了线材质量.

     

    Abstract: In order to restrain the harmful effects of load disturbance on the high speed wire rod continuous rolling mill by direct current speed governing system, a discrete load disturbance observer and forward feedback disturbance compensation direct current speed governing system were applicated, and the restructured load fluctuation was applied to minute tensile force control. The experiment on the spot showed that the designed system improves the dynamic and static performance of the speed governing system, lower the dynamic and static state velocity jump and loss, so the quality of rolling wire is improved much more, and reduce the rate of waste production.
