带钢纠偏系统的自抗扰控制

Active Disturbance Rejection Control of Steel Strip Deflection Correction System

针对带钢在处理线上运行时发生左右偏移的现象,建立纠偏控制系统动态模型。针对带钢纠偏系统具有操作条件变化快、外界扰动多和工业控制器无法有效抗扰等问题,提出基于自抗扰控制方法的带钢位置控制策略,总结出控制器参数整定规则,并对带钢纠偏控制系统进行仿真,验证了控制方案的有效性。

To describe the phenomenon of the left and right deviation in the strip steel processing line,aposition dynamic model of the deviation correction system is then built.Considering the rapid change in operating conditions of the deviation correction system,multi-disturbance nature and the industrial controller cannot resist disturbance effectively,aposition control method based on the active disturbance rejection control（ADRC）strategy is presented.Meanwhile,the parameter tuning rules for this ADRC method is concluded.Finally,simulation results of the deviation correction system for strip steel show the effectiveness of the proposed method.
