In this paper, an adaptive fault tolerant control (FTC) scheme based on barrier Lyapunov functions (BLFs) for the hypersonic flight vehicle (HFV) with state constraints is proposed. Complexities of the aerodynamical uncertainties, external disturbances and flexible dynamics are taken into account in the controller design process. The paper deals with the MIMO system properly so that the backstepping technique based on BLFs can be successfully used for the issue of state constraints without neglecting the coupling of HFV system. To aim at the unknown faults of the elevators, an adaptive FTC mechanism is introduced to the BLFs-based controller, which increases the reliability of the system. Finally, simulations are conducted to verify the validity of the designed controller.

具有状态约束的高超音速飞行器系统的自适应容错控制

针对具有状态约束的高超音速飞行器,提出了一种基于屏障李雅普诺夫函数(BLF)的自适应容错控制方案。在控制器设计过程中考虑了空气动力学不确定性,外部干扰和灵活动力的复杂性。本文对MIMO系统进行了适当的处理,使得基于BLF的反推技术可以成功地用于状态约束问题,而不会忽略HFV系统的耦合。为了针对电梯的未知故障,将自适应FTC机制引入基于BLF的控制器中,从而提高了系统的可靠性。最后,进行仿真以验证所设计控制器的有效性。
