Abstract :
A novel industrial approach on application of μ-synthesis controller based on Quantitative Feedback Theory (QFT) tuning strategy for plate rolling Automatic Gauge Control (AGC) system is proposed in this paper. To the mill stiffness uncertainties and nonlinear parts, the dual-perturbation AGC model design is presented. The integration of optimal μ-synthesis and manual tuning in the QFT design environment enables the controller design with a high level of robust performance and robust stability. The Data information is better analyzed with the modified tuning theory in industrial field. Simulations were carried out to evaluate the effectiveness of the proposed control method which applied to 2 500 mm plate rolling process.
