Generic Homotopic Smoothing for Low-Thrust Optimal Control Problems With Power Constraints

Q Xiao, L Li, J Zhang, M Xu - IEEE Transactions on Control …, 2024 - ieeexplore.ieee.org
This brief is devoted to the power-constrained low-thrust optimal control problem (OCP).
First, a general model for a class of power constraints is proposed by defining a piecewise …

Direct optimization of low-thrust orbit-raising maneuvers using adjoint sensitivities

A Arustei, A Dutta - Acta Astronautica, 2024 - Elsevier
This paper considers the problem of optimizing minimum-time and minimum-propellant
many-revolution low-thrust geocentric orbit-raising maneuvers to an arbitrary target. The …

A simplified analytical approach for determining eclipses of satellites occulted by a celestial body

V Zubko, A Belyaev - Acta Astronautica, 2024 - Elsevier
The primary objective of this paper is to construct an analytical model for determining the
total duration of eclipse events of satellites. The approach is based on the assumption that …
