中文摘要
      变体飞行器在不同的机体构型有不同的控制目标, 针对变体飞行器的多目标控制问题, 提出了一种切换线 性变参数(linear parameter varying, LPV)控制方法. 该方法根据变体飞行器的任务模式及性能指标要求把后掠角变 化范围分成不同的区域, 在不同的区域根据相应的控制目标求出系统满足控制性能指标的有解条件及相应 的LPV控制器, 并用参数依赖多Lyapunov函数和公共Lyapunov函数两种方法保证变体过程的稳定性及快速性. 仿真 结果表明: 在飞行器参数大范围快速变化的情况下, 运用本文设计的控制器具有良好的操纵性能.
英文摘要
      A morphing aircraft has different control objectives in different configurations. For the multi-objectivecontrol problem of the morphing aircraft, we propose a switching linear parameter varying (LPV) control method in which the range of the sweep angle is divided into sub-regions according to the flight modes and design objectives. The solvability condition of the problem with a given control performance indices is established, and a family of LPV controllers is designed accordingly. The design is based on either the multiple parameter-dependent Lyapunov functions or the common parameterdependent Lyapunov function, which ensures the stability of the transition phase in the rapid morphing process under the restrictions of the morphing mechanism. Simulation results show that the designed controller can guarantee the excellent control performance of the morphing aircraft in its wide range of parameter values.
