Tilt-Rotor Vertical Takeoff and Landing UAV Oblique Takeoff Trajectory Optimization

In this paper, for the tilt-rotor vertical takeoff and landing vehicle takeoff multi-constraint trajectory optimization problem, the optimal takeoff trajectory optimization design based on the Gauss pseudo-spectral method is carried out, and the optimal takeoff trajectory of energy consumption and time is derived. The optimal control problem model of the tilted takeoff optimal trajectory optimization problem is established, discretized by Gauss pseudo-spectral method, and transformed into a nonlinear planning problem for solving. The mathematical simulation results show that the optimization result meets the constraints, reaches the target landing point with zero speed, and meets the optimization objective of optimal fuel consumption.
