Therefore, steady glide trajectory is the best reference trajectory for the reentry guidance.
Additionally, a study on steady glide trajectory optimization is investigated based on this new modeling.
Moreover, the glide trajectory is similar to the reference trajectory except that the trajectory oscillation is suppressed.
In this section, the steady glide trajectory optimization is carried out to find the optimal controls satisfying path and final constraints.
If [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] are given, there exists a specific steady glide trajectory determined by the steady glide dynamic modeling.
Steady glide trajectory optimization problem for high lift-drag ratio reentry vehicle is a complex constrained continuous-time optimal control problem.
In this subsection, Hp-adaptive Gaussian quadrature collocation method is applied to solve the steady glide trajectory optimization problem.
Generally speaking, the objective of steady glide trajectory optimization is to provide reference trajectory for traditional entry guidance such as linear-quadratic regulator tracking laws.
Obviously, the steady glide trajectory optimal control problem formulated in this paper can be solved by Hp-adaptive pseudospectral solver with a very high efficiency.
Based on this new modeling, a study on steady glide trajectory optimization with multiple final constraints is investigated.
