摘　　要：AOD烘烤过程中,为合理控制燃气量和空气量的比例关系,比较了串级比值控制、空气限幅控制和双闭环交叉限幅控制方案,仿真结果表明,双闭环交叉限幅控制在燃气升负荷和降负荷的过程中能维持合适的空燃比。To balance the ratio between the amount of gas and air quantity in the AOD backing process, we compare the three control methods which are cascade ratio control, air limiting control and double closed-loop cross-limiting ratio control, and the simulation results show that the double closed loop cross limiting control is optimal to keep the suitable air-fuel ratio.

关 键 词：AOD烘烤 温度串级 双闭环交叉限幅控制
