摘要
基于模糊自适应控制方法设计了轧机厚控APC(AutomaticPositionControl)的滑模跟踪控制器,在系统动态函数未知的情况下,运用动态模糊逻辑系统DFLS(DynamicFuzzyLogicSystem)以及自适应机构构造变结构控制;应用李亚普诺夫方法设计滑模系数以及变结构控制律参数,使得闭环系统渐近稳定;不需要轧机APC的精确数学模型。仿真结果验证了控制系统的有效性以及抗干扰性能。
An adaptive sliding mode tracking controller based on fuzzy identifications for automatic position control (APC)in cooling mills is studied. In the case of the unknown precise model, dynamic fuzzy logical system (DFLS) is introduced to form the sliding mode controller. Then based on Lyapunov theory, the stability of the closed-loop system is proved. Finally, simulation results show the validity of the controller under various perturbations.
