Spacecraft attitude control: Application of fine trajectory linearization control [PDF]
Advances in Space Research, 2021 Abstract One of the simplest and most popular methods to design a model-based controller for a nonlinear dynamic system is to apply linear control theories to the linearized model of the nonlinear system. For linearization, first-order Taylor series expansion is a straightforward and widely used method.

Attitude Control of Two-Wheel Spacecraft Based on Dynamics Model via Hierarchical Linearization
SICE Journal of Control, Measurement, and System Integration, 2017 In this paper, we propose an attitude control law for underactuated two-wheel spacecraft under non-zero total angular momentum. Attitude control with non-zero total angular momentum is complicated in the case that the number of reaction wheels equipped ...
