“…5. In contrast with the previously investigated control solutions, [7] and [8], where the closedloop system resulted incapable of recovering from instability consequent to actuation torque saturation, starting at target angle θ c ≈ 10[deg]; obtained results, for the proposed adaptive control strategy, confirm that even for long lasting saturation of the wheel, system convergence is still guaranteed both for large step and square wave, omitted here, tracking signal. However, a larger overshoot, and longer settling time, impossible to counteract due to the actuation system limitations, characterize the time response leading to unacceptable performances, starting at θ c = 25[deg].…”

“…II, the physical system under analysis can be modeled as multiple LTI system for different Λ values leading to the formulation reported in Eqs. ( 6) and (7). To the objective of designing a model reference control law, both representations can be considered as sub-classes of a more general continuous-time, nonlinear and eventually unknown plant description, which can be expressed in an amenable form as:…”

“…In this framework, while preliminary results on Low Earth Orbit (LEO) small-sized satellites were very promising, reaction wheels saturation and coupling dynamics with flexible appendices remain unresolved issues [7], [8]. These dynamics can no longer be neglected in the case of geostationary (GEO) or interplanetary mission satellites, which are typically equipped with significantly larger solar arrays structures and propellant tanks.…”

In a scenario of always more complex and demanding space missions, enhanced attitude control systems play a key role for satellite design and capabilities improvement. In this paper, an adaptive and robust solution to the pointing angle tracking problem under mixed sources of disturbances is presented. A valid simplified parametric model, of a single axis satellite dynamics, is firstly introduced and discussed, to the objective of effectively accounting for propellant slosh and flexible appendices torque perturbations. The control problem is subsequently solved with a model reference adaptive control approach, namely the Minimal Control Synthesis (MCS). Theoretical fundamentals, architecture implementation and final tuning are reported. A subset of the extensive validation campaign performed is presented and discussed to demonstrate the impressive robustness and performance level reached by the proposed scheme. Limitations and future perspective to tackle them conclude the paper.

This paper presents open challenges and perspectives of propellant management for crewed deep space exploration. The most promising propellants are liquid hydrogen and liquid methane, together with liquid oxygen as an oxidizer. These fluids remain liquid only at cryogenic conditions, that is, at temperatures lower than 120 K. To extend the duration of space exploration missions, or even to enable them, the storage and refueling from a cryogenic on-orbit depot is necessary. We review reference missions, architectures, and technology demonstrators and explain the main operations that are considered as enablers for cryogenic storage and transfer. We summarize the state of the art for each of them, showing that many gaps in physical knowledge still need to be filled. This paper is based on recommendations originally proposed in a White Paper for ESA’s SciSpacE strategy.
