摘　　要：基于鲁棒结构奇异值μ理论,建立了热轧带钢AGC的鲁棒控制模型,把AGC系统中分散的摄动集中成一个对角阵进行描述,分析了μ综合控制在热轧带钢中的摄动抑制机理,应用鲁棒稳定与鲁棒性能准则约束条件,设计了热轧带钢AGCμ控制器.仿真结果表明μ综合控制能有效地抑制AGC系统中的摄动,对模型不确定性具有很好的鲁棒性.Based on structural singular value 1 theory, dispersive perturbation in AGC system is concentrated to a diagonal matrix, the robust control model for AGC system in hot rolling processing is built, and the disturbance attenuation mechanism of 1 synthesis is analyzed. The 1 synthesis controller for AGC system is designed by adopting robust stabilization and robust performance restriction rule. The simulation results indicated that 1 synthesis control is effective on disturbance attenuation under the condition of perturbations.
