摘要:

针对高超声速飞行器在模型不确定、外部干扰和执行机构故障影响下的姿态控制问题,提出了一种考虑预设性能的非奇异快速终端滑模容错控制方法。首先,基于姿态运动模型和执行机构故障模型建立了面向容错控制的模型,并利用预设性能函数对姿态跟踪误差系统的瞬态和稳态性能进行定量化设计;其次,设计了新型滑模干扰观测器对由模型不确定、外部干扰和执行机构故障组成的复合干扰进行精确估计;然后,以复合干扰的估计值作为补偿设计了非奇异快速终端滑模容错控制器,并利用Lyapunov稳定性理论证明了闭环系统的稳定性;最后,仿真结果验证了该方法具有较好的容错性能。

Abstract:

Aiming at the attitude control problem of hypersonic vehicle under the influence of model uncertainties, external disturbances and actuator faults, a non-singular fast terminal sliding mode fault-tolerant control method considering prescribed performance is proposed. Firstly, a fault-tolerant control model is established based on the attitude motion model and the actuator faults model, and the transient and steady-state performance of the attitude tracking error system is quantitatively designed by using the prescribed performance function. Secondly, a novel sliding mode disturbance observer is designed to accurately estimate the compound disturbances composed of model uncertainties, external disturbances and actuator faults. Then, a non-singular fast terminal sliding mode fault-tolerant controller is designed with the estimated value of the compound disturbances as compensation, and the stability of the closed-loop system is proved by the Lyapunov stability theory. Finally, simulation results show that the proposed method has good fault tolerance performance.

Key words: hypersonic flight vehicle, attitude fault-tolerant control, sliding mode disturbance observer, non-singular fast terminal sliding mode control, prescribed performance control
