摘　　要：针对变体飞行器姿态控制系统,提出一种基于双层多面体描述的LPV多目标控制器,同时考虑调度参数的变化和系统不确定性的影响。第一层多面体用于管理调度参数并在顶点不确定系统上设计增益调度控制器;第二层多面体建立在每个顶点系统上以进行闭环控制系统的鲁棒设计。上述控制器求解问题最终可转化为求解一组有限数量的线性矩阵不等式。仿真结果表明,在所设计控制器作用下,变体飞行器系统可较好的跟踪攻角参考信号,同时具有良好的鲁棒性能。This paper studies the design of LPV multi-objective controller based on double-layer polytopic description morphing aircraft attitude system against the effects of scheduling parameters and system uncertainties.The first polytopic layer manages varying parameters and designs gain scheduling controllers on each vertex uncertain system;the second polytopic layer is built on each vertex system for robust design of closed-loop control systems.The designed problem can be transformed into solving a finite number of linear matrix inequalities.The simulation results show that the morphing aircraft system can better track the angle of attack reference signal and has good robust performance against the system uncertainty under the proposed controller.
