In this paper, a practical decoupling control scheme for fighter aircraft is proposed to achieve high angle of attack (AOA) tracking and super maneuver action by utilizing the thrust vector technology. Firstly, a six degree-of-freedom (DOF) nonlinear model with 12 variables is given. Due to low sufficiency of the aerodynamic actuators at high AOA, a thrust vector model with rotatable engine nozzles is derived. Secondly, the active disturbance rejection control (ADRC) is used to realize a three-channel decoupling control such that a strong coupling between different channels can be treated as total disturbance, which is estimated by the designed extended state observer. The control surface allocation is implemented by the traditional daisy chain method. Finally, the effectiveness of the presented control strategy is demonstrated by some numerical simulation results.

基于ADRC的飞机高迎角解耦控制

本文提出了一种实用的战斗机解耦控制方案，利用推力矢量技术实现大迎角（AOA）跟踪和超级机动动作。首先，给出了一个具有 12 个变量的六自由度 (DOF) 非线性模型。由于在高迎角下气动执行器的不足，推导出具有可旋转发动机喷嘴的推力矢量模型。其次，利用自抗扰控制（ADRC）实现三通道解耦控制，将不同通道之间的强耦合视为总扰动，由设计的扩展状态观测器估计。控制面分配采用传统菊花链方式实现。最后，
