为了提高板厚控制系统的智能化程度，提出了基于T-S模糊模型的冷带轧机板厚控制系统模糊预测控制策略。在板厚控制系统T-S模糊模型辨识的基础上，采用基于广义预测控制的模糊预测控制算法求解控制律，弥补了规则型模糊控制器的不足。利用板厚控制系统T-S模糊模型离线求解模糊预测控制器的规则库，采用强度转移法求解输入信号相对于规则库的隶属度函数值，避免了Diophantine方程的在线递推求解，降低了控制算法的复杂性，提高了实时性。轧制试验结果表明，所提出的控制策略有效改善了板厚控制系统的性能，提高了冷轧带钢的板厚控制精度。

The fuzzy predictive control strategy is provided to improve the intelligent level of the automatic gauge control system of the cold rolling mill based on the T-S fuzzy model. After the T-S fuzzy model identification of the automatic gauge control system, the control rule is gained by the fuzzy predictive control algorithm based on the generalized predictive control and the shortage of the regulation fuzzy controller is overcomed. The T-S fuzzy model of the automatic gauge control system is used to gain the rule base of the fuzzy predictive control offline. The intensity-transferring method is adopted to get the value of membership grade function between the input and the rule base, the online calculation of Diophantine equation is avoided,the complexity of algorithm is reduced,and the timeliness is improved. Rolling experimental results show that the control strategy improves the performance of the automatic gauge control system and the gauge control precision of the cold rolling strip.
