Trajectory Convex Optimization Method of Civil Aircraft Landing Based on Chebyshev Collocation Method

This paper studies the optimal flight path planning of civil aircraft in the landing stage and carries out simulation verification. The six degrees of freedom model of civil aircraft is established and the landing path of civil aircraft is planned by serial convex optimization method. The optimization loss function is defined from the perspective of energy, the convexity of civil aircraft motion equation is completed by linearization, and the calculation amount of solution is reduced by Chebyshev collocation method. The flight path planing strategy is verified by simulation of Boeing aircraft model.
