论文摘要
本文提出了一种适应固定翼飞机的自适应自动驾驶仪，并将其性能与固定增益自动驾驶仪进行了比较。自适应自动驾驶仪是通过使用自适应控制定律扩大自动驾驶架构来构建的，这些法律使用回顾性成本自适应控制进行更新。为了调查自适应自动驾驶仪的性能，固定增益自动驾驶仪的默认增益被缩放以降低其性能。这种情况为确定自适应自动驾驶仪补偿降级固定增益自动驾驶仪的能力提供了一个场所。接下来，通过模拟一个场景，认为其中一个对照表面被认为被卡在未知角度的情况下，对自适应自动驾驶仪的性能进行了检查。在降解的社会条件下，还在物理飞行实验中测试了自适应自动驾驶仪，并检查了所得的性能改善。
This paper presents an adaptive autopilot for fixed-wing aircraft and compares its performance with a fixed-gain autopilot. The adaptive autopilot is constructed by augmenting the autopilot architecture with adaptive control laws that are updated using retrospective cost adaptive control. In order to investigate the performance of the adaptive autopilot, the default gains of the fixed-gain autopilot are scaled to degrade its performance. This scenario provides a venue for determining the ability of the adaptive autopilot to compensate for the degraded fixed-gain autopilot. Next, the performance of the adaptive autopilot is examined under failure conditions by simulating a scenario where one of the control surfaces is assumed to be stuck at an unknown angle. The adaptive autopilot is also tested in physical flight experiments under degraded-nominal conditions, and the resulting performance improvement is examined.
