On January 25,2020,Boeing's new 777X commercial airplane finally took its maiden flight at Everett,Washington's Paine Field,after a long wait due to a series of development delays and a postponement of its first flight since it was launched in November 2013.Boeing 777X is the latest series of the long-range,wide-body,twin-engine Boeing 777 family. According to Boe-

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.
