摘要
通过对飞控系统模型特点的分析,以及模糊控制稳定性条件的深入研究,基于线性T-S模型的模糊控制系统稳定性条件,建立了飞控系统的线性T-S模糊模型,并利用现代控制理论中的状态反馈方法,结合并行分布补偿(PDC)的思想,借助求解一组线性矩阵不等式(LM I)等设计了一种模糊控制器,所设计的控制器能保证闭环系统的全局渐近稳定,并具有较好的鲁棒性。以一个仿真实例验证所设计的模糊控制器的鲁棒性。该方法对于飞控系统鲁棒控制律的设计、故障诊断、控制系统重构具有一定的参考意义。
This paper analyzes model of the flight control system and discusses the stability condition of fuzzy control system. Based on the stability condition of T-S linear model in fuzzy control systems, a T-S fuzzy model is established. Using state feedback method in the modern control theory and idea of parallel distributed compensation （PDC）, a fuzzy controller is obtained through solution of a group of linear matrix inequalities （LMI）. The controller with good robustness can ensure the globally asymptotic stability of closed loop control system. A simulation model is designed to verify robustness of the controller. This method gives a reference to the design, failure diagnosis and control system reconstruction of the controller.
