| Resumo: | We propose a reachability approach for infinite
and finite horizon multi-objective optimization problems for
low-thrust spacecraft trajectory design. The main advantage
of the proposed method is that the Pareto front can be
efficiently constructed from the zero level set of the solution
to a Hamilton-Jacobi-Bellman equation. We demonstrate the
proposed method by applying it to a low-thrust spacecraft
trajectory design problem. By deriving the analytic expression
for the Hamiltonian and the optimal control policy, we are
able to efficiently compute the backward reachable set and
reconstruct the optimal trajectories. Furthermore, we show
that any reconstructed trajectory will be guaranteed to be
weakly Pareto optimal. The proposed method can be used as a
benchmark for future research of applying reachability analysis
to low-thrust spacecraft trajectory design. |
