摘要
姿态匹配传递对准对机翼弹性变形很敏感,若机翼弹性变形建模不当,将造成姿态匹配传递对准卡尔曼滤波性能的恶化。由于H∞滤波对系统的不确定性干扰具有很强的鲁棒性,因此本文将机翼的弹性变形视为姿态匹配传递对准中量测的不确定性干扰,并且设计了姿态匹配传递对准的H∞滤波器。仿真结果表明,在不对机翼弹性变形进行建模的情况下,姿态匹配传递对准的H∞滤波器能在十多秒钟的时间内完成传递对准,并且传递对准精度可达5′。
The attitude matching transfer alignment is sensitive to the wing flexibility. If the model of the wing flexibility is fault, the Kalman filter performance of the attitude matching transfer alignment should be deteriorated. The H_∞ filter is robust to the uncertain disturbance of the system. In this paper, the H_∞ filter for the attitude matching transfer alignment is designed and the wing flexibility is considered as the uncertain disturbance measured in the attitude matching transfer alignment. Simulation results show that the H_∞ filter for the attitude matching transfer alignment can accomplish the transfer alignment within about ten seconds and the accuracy of the transfer alignment can be less than five angular minutes without the model of the wing flexibility.
