| 本文提出了一种执行器故障的舰载机着舰容错控制系统，该系统可有效抑制着陆过程中的外界干扰和执行器故障带来的不利影响。首先，利用基于最小二乘的自回归模型对甲板运动进行预测，以获得在波浪干扰下的准确落点；其次，设计了下滑路径导引律，利用该导引律生成飞行航迹角；此外，设计了基于干扰观测器的快速终端积分滑模控制器，利用低通滤波器实现了控制器串联设计；最后，通过李雅普诺夫函数证明了该容错控制方法的跟踪误差一致有上界。将本文方法与比例-积分-微分控制器进行了对比数值仿真，验证了该算法的可行性。 |
| 英文摘要: |
| This paper presents a landing fault-tolerant control system for carrier-based aircraft with faulty actuators. The system can effectively suppress the external disturbance during landing and the adverse effects caused by faulty actuators. First， an autoregressive model based on least squares is used to predict the deck motion to obtain the accurate landing point under wave disturbances. Second， a glide path guidance law is designed to generate the flight path angle. In addition， fast terminal integral sliding mode controllers based on disturbance observers are designed， and the controllers are connected in series with low-pass filters. Finally， the Lyapunov function is utilized to prove that the tracking error of the fault-tolerant control method is uniformly upper bounded. The proposed method is compared with the proportional-integral-differential （PID） controller by the numerical simulation， and the results verify the feasibility of the proposed algorithm. |
