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

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.
