摘　　要：针对推力矢量飞机超机动飞行过程中的参数摄动和舵面故障问题,提出了一种基于终端滑模的容错控制律设计方法。首先给出了推力矢量飞机的舵面故障模型,然后分别针对姿态角回路和角速度回路设计了终端滑模容错控制律,并引入投影自适应律对参数摄动和舵面故障进行估计和补偿,最终得到舵面偏转指令信号,并对系统进行Lyapunov稳定性分析。通过Matlab/Simulink对比仿真,验证了提出的容错控制律能够实现包容参数摄动和舵面故障的超机动飞行,且自适应律能够准确估计舵面故障。Aiming at the parameter perturbation and rudder surface faults in supermaneuver flight of thrust vector aircraft,a fault-tolerant control method based on terminal sliding-mode is proposed.Firstly,the rudder surface fault model of thrust vector aircraft is given.Then,the terminal sliding-mode control laws are designed for the attitude angle loop and angle velocity loop respectively,and the projection adaptive law is introduced to estimate and compensate for the parameter perturbation and the rudder surface faults.Finally,the rudder deflection command signal is obtained,and the Lyapunov stability analysis of the system is carried out.The Matlab/Simulink simulation results verify that the proposed fault-tolerant control law can realize the tolerance for parameter perturbation and rudder surface faults of supermaneuver flight,and the adaptive law can accurately estimate the rudder faults.
