The attitude dynamics of spacecraft are highly nonlinear, which makes it challenging to design control algorithms that can handle these nonlinearities. This study presents a novel data-driven synthesis method for using the LightGBM controller. controller is designed by supervised machine learning methodologies. training and testing datasets generated from input-output data closed-loop system un...

Small satellites are now capable of performing missions that require accurate attitude determination and control. However, low size, power, and cost requirements limit the types of attitude sensors that can be used on a small craft, making attitude estimation difficult. In particular, star trackers—often the attitude sensors of choice for larger spacecraft—are not practical for small satellites...

This paper extends the continuous inertia-free control law for spacecraft attitude tracking derived in prior work to the case of three axisymmetric reaction wheels. The wheels are assumed to be mounted in a known and linearly independent, but not necessarily orthogonal, configuration with an arbitrary and unknown orientation relative to the unknown spacecraft principal axes. Simulation results ...
