针对多变量耦合系统,提出了一种新的广义预测解耦控制算法.通过广义预测误差权值自动调节以消除系统耦合引起的误差,从而降低系统的耦合影响,提高系统性能.该方法与常规的多变量广义预测控制算法相比,算法简单,计算量小.本文所设计的算法被应用到热轧带钢板形板厚控制系统中,仿真结果表明了该算法的有效性和正确性.

A control method based on generalized predictive control（GPC） was proposed for a multivariable coupling system,Error weights could be self-regulated in order to reduce interactions in the system and improve dynamic performances of coupling loops.Compared with the conventional multivariable generalized predictive,the proposed method is characteristic of simplicity and small computational burden.The algorithm was applied to an auto-shape control and auto-gauge control system（ASC-AGC）,and simulation results demonstrate its efficiency and correctness.
