“…14,15 Various control schemes have been proposed for the underactuated attitude or relative orbital control problem by different approaches. For the underactuated attitude control category, Alberto et al 16 designed an optimal time controller for underactuated spacecraft with reaction wheels and thrusters installed in two control axes. An optimization-based motion planning approach proposed by Ali Mehrparwar et al 17 is applied to control an underactuated spacecraft with the non-diagonal inertia matrix and two reaction wheels.…”

This work proposes a saturation control scheme for underactuated spacecraft formation reconfiguration in elliptic orbits without radial or along-track thrust. Firstly, the rank criterion method is applied to analyze the controllability and feasibility of formation reconfiguration by linearizing the linear time-varying dynamics to linear time-invariant ones. Based on the inherent coupling of the linear time-varying system, the underactuated error dynamics are presented for either underactuated case. Subsequently, the developed underactuated saturation controller can ensure that the time-varying system trajectory asymptotically converges to the specified configuration. The Lyapunov-based analysis presents the constraint conditions of controller parameters and the stable reconfiguration accuracy of the system states. Finally, numerical simulations for both underactuated scenarios are performed in the environment with J2 perturbation to verify the validity of the proposed underactuated control scheme.

“…Leach (2013) reviewed the early failures of spacecraft attitude control systems under the influence of geomagnetic storms and electrostatic discharge (Table 1). In recent space missions, spacecraft such as the Hubble telescope, the Odyssey Mars probe, the Dawn and the Hayabusa have also experienced attitude control system malfunctions (Dennehy, 2014; Olivares and Staffetti, 2018). Typically, the momentum wheel of the x - and y -axes successively failed during the Hayabusa mission, leading to the satellites being in an underactuated situation with two controls, which is the underactuated type considered in this paper.…”

This paper aims to address attitude stabilization control of an underactuated post-capture combination and achieve test validation based on the magnetism–buoyancy hybrid micro-gravity experiment system (MBHMES). Using a precise reduced model, a cascade control law is proposed to solve the issue theoretically. First, an advanced quaternion-based kinematic control law is proposed to stabilize the attitude of the non-symmetric post-capture combination. This control law can overcome the singularity brought about by the small initial attitude under the consideration of uncontrolled angular velocity. Then, considering the existence of multiple disturbances introduced by the fluid flow and electromagnetic force, an effective adaptive dynamic controller is proposed to meet the attitude requirement and reduce the negative effect of the multiple disturbances. For test demonstrations, a scenario of a base body capturing the target with robotics, to achieve attitude stabilization expectation, is described. Simulation results demonstrate the performance of the cascade control laws and test data show the effectiveness of the proposed method.

“…To deal with the attitude stabilization problem, significant efforts have been made in recent years, and a series of nonlinear control algorithms is developed for three-axis attitude control of fully actuated spacecraft (see slidingmode control [1], [7], [8]; backstepping control [4]; adaptive control [9]; hybrid control [10]; and inverse optimal control [11]). Furthermore, some control techniques are also adopted for the underactuated case, such as model predictive control [12], hybrid time-optimal control [13], and switching control [14]. Under ideal conditions, namely, without modeling uncertainties and actuator malfunctions, etc., these methods are able to achieve and maintain decent control performances.…”
