摘    要：针对多变量耦合系统,提出了一种基于解耦的时滞递推滑模预测控制的算法。该算法是在对角解耦的基础上,将预测算法和递推滑模控制结合起来,设计了递推滑模预测控制器。还对滑模参考轨迹进行了研究和分类,阐述了两种滑模参考轨迹的区别。该算法被应用在带钢板形板厚的控制过程中,试验和仿真结果表明,该方法可较好地消除带钢板形板厚控制中耦合与时滞的影响。

Abstract: For multivariable system with time-delay,the recursive sliding mode predictive decoupling method was designed.This method combines predictive control with sliding mode control for multivariable system which is diagonally decoupled.The recursive sliding reference trajectory was studied and classified.The differences of two types of reference trajectories can be illustrated.Proposed method can be applied to a strip shape and gauge control system(ASC-AGC).Experiment and simulation results show that this method may be better to depress the coupling and time delay of ASC-AGC control system.
