“…Despite its intuitive interpretation, it seems that formally showing desirable stabilization properties of the overall controller (6), (14), (16) is not so straightforward. Some directions are given with respect to this in [3], [4], [6], [9], [15], [23] where a frequency separation argument is required between the two loops cited above, which corresponds to selecting a very aggressive action of the attitude stabilizer (14). This can be performed, for example, by selecting sufficiently large gains c and K ω in (6).…”

Considering the most widely spread configuration of actuators for low orbit satellites, namely a set of reaction wheels and a set of magnetorquers, we revisit the classical "cross product control law" solution for achieving attitude stabilization and momentum dumping. We show how the classical solution has a quasi-cascade structure that, under a suitable input-tostate (ISS) assumption, can be stabilized by high gain, thereby making the actuators more inclined to saturate. Motivated by this, we propose a revisited version of this control law that transforms the quasi-cascade into a real cascade. Then we show that both strategies are such that the attitude control is affected by the momentum dumping, and that they both require a suitable ISS property. To overcome these drawbacks, we propose a new allocation-based controller which makes the attitude dynamics completely independent of the momentum dumping and induces global asymptotic stability without any ISS requirement. Several formal statements and simulation results support our discussions and highlight the pros and cons of the different control strategies.

“…In addition to these, Hablani [7] proposed a linear orbit-averaged magnetic controller using pole placement technique, Burns and Flashner [8] proposed a model reference adaptive scheme, Lovera [9] proposed a magnetic momentum unloading control law using optimal control theory, and Iida and Ninomiya [10] presented a non-linear magnetic control law using estimated environmental disturbance torque. The aforementioned studies mainly are limited to low Earth orbit spacecraft; in a recent study [11], robustness of a cross-product control law applied to a geostationary Earth orbit spacecraft (due to the unpredictable nature of magnetic field at this altitude) has been investigated.…”

An approach for the design of a momentum unloading system for a spacecraft controlled by momentum exchange actuators is proposed. The approach is based on formulating momentum unloading as a control problem of a parametrically perturbed periodic system. An equivalent discrete-time robust control design problem is formulated using a point-mapping-based numerical algorithm. Established robust control analysis can then be used to develop and analyse the robustness of the unloading control law. The method is demonstrated on an Earth-pointing satellite with magnetic torquers serving as unloading actuators. Earth's magnetic field is modelled as a tilted dipole that consists of a periodic term and bounded perturbations. A discrete-time representation of the system is used to develop an unloading control law and the structured singular value theory is employed to analyse its robustness to parametric uncertainties.
