摘要: 为了解决再入飞行过程中, 飞行器故障时的姿态控制问题。提出了一种故障检测策略和在故障状态下的姿态控制方法。首先, 设计了非线性故障检测观测器, 通过姿态角观测误差阈值确定故障是否发生。其次, 使用自适应控制技术和滑模控制技术实现了故障情况下的再入飞行器姿态控制。最后, 通过数值仿真算例, 测试了经典双回路控制律和提出的容错控制律下的姿态指令跟踪效果, 证明了提出的容错控制策略的有效性。

Abstract: In order to satisfy the requirements of reentry vehicle attitude control under the uncertain fault and improve the robustness and adaptability of reentry control, a fault detection strategy and a attitude control method with actuator fault are introduced.For the dynamic model of reentry vehicle in fault case, a fault detection scheme is proposed by designing a nonlinear fault detection observer.An active tolerant tracking strategy is presented by making use of both adaptive control and sliding mode control techniques.Finally, simulation results are given to demonstrate the effectives of the developed fault tolerant control scheme.

Key words: reentry glide, attitude control, slide mode observer, fault diagnosis, fault tolerant control
