Abstract EN
Of the many direct numerical methods, the pseudospectral method serves as an effective tool to solve the reentry trajectory optimization for hypersonic vehicles.
However, the traditional pseudospectral method is time-consuming due to large number of discretization points.
For the purpose of autonomous and adaptive reentry guidance, the research herein presents a multistage trajectory control strategy based on the pseudospectral method, capable of dealing with the unexpected situations in reentry flight.
The strategy typically includes two subproblems: the trajectory estimation and trajectory refining.
In each processing stage, the proposed method generates a specified range of trajectory with the transition of the flight state.
The full glide trajectory consists of several optimal trajectory sequences.
The newly focused geographic constraints in actual flight are discussed thereafter.
Numerical examples of free-space flight, target transition flight, and threat avoidance flight are used to show the feasible application of multistage pseudospectral method in reentry trajectory optimization.
