摘要：
Thrust-vectored vertical and/or short take-off and landing (V/STOL) aircraft which combines the merits of fast cruise speeds and take-off flexibility has attracted much attentions those years. Firstly, this paper builds the aerodynamic model of thrust-vectored V/STOL aircraft including saturation of actuators. Secondly, aiming at the characteristic of strong coupling and strong nonlinearity faced by transition process, optimal trajectories for V/STOL aircraft transitions is generated through gradient descent method and the computing process is accelerated by adaptive moment (Adam) algorithm. Thirdly, a new method has been designed in this paper which takes optimal trajectory as a special feedforward which will be compensated according to the real flight states. Through a series of simulation, the performance of the proposed method is verified and it can be easily seen that this method has the advantages of short time, stable attitude and strong robustness during transition process. © 2020, Editorial Department of Control Theory & Applications South China University of Technology.
