| 摘要: |
| 运用切换线性变参数(linear parameter varying, LPV)的控制方法解决变体飞行器在不同机翼构型有不同的控制目标问题。首先根据变体飞行器的任务需求把后掠角变化范围分成不同的区域,针对不同的变化区域分别设计相应的LPV控制器,采用参数依赖公共Lyapunov函数方法实现在变形机构允许的范围内以尽可能快的变体速度实现变体过程。仿真结果表明用所用方法设计的控制器具有良好的响应特性,可实现对指令信号的良好跟踪。 |

| Abstract: |
| A switching linear parameter varying (LPV) system was applied to deal with multiple design objectives during the flight of morphing aircraft. A group of LPV controllers are then designed based on common parameter-dependent Lyapunov function and each of them is suitable for a specific subregion of the sweep angle; the process can be accomplished quickly within the permission of the morphing mechanism under the common parameter-dependent Lyapunov function scheme. The simulation results show that the controller designed in this paper can make the morphing aircraft have good response characteristics and tracking of command signal. |
