本文提出了一种基于解耦的时滞递推滑模预测控制的算法并将其应用在带钢板形板厚的控制过程中。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。理论分析和仿真结果表明，本文方法可较好地消除滑模抖振现象和系统的时滞，从而避免带钢板形板厚控制中耦合与时滞的影响。另外，本文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。
For multivariable system with time-delay, recursive sliding mode predictive diagnol decoupling method is designed. This method combines predictive control and sliding mode control and can be applied to a strip shape and gauge control system. The simulation results and the theoretical analysis is given to demonstrate the correctness and effectiveness of approach which can eliminate chattering and system time-delay. The coupling between shape control and gauge control is depressed. In this paper, the recursive sliding reference trajectory is studied and classified, the differences of two types of reference trajectories can be illustrated
