Robust μ synthesis control for AGC system in hot rolling processing
基于结构奇异值μ综合的热轧带钢AGC鲁棒控制

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.
