2008 conference paper
Robust design of a spacecraft attitude tracking control system with actuator uncertainties
2008 47th IEEE Conference on Decision and Control. Presented at the 2008 47th IEEE Conference on Decision and Control.
Event: 2008 47th IEEE Conference on Decision and Control
TL;DR:
The robust redesign for transient performance recovery of nonlinear systems with input uncertainties developed in [2] is applied to a spacecraft attitude tracking problem with actuator uncertainties and it is shown that when the spin and transverse axis directions and/or the gains of the flywheel actuators are uncertain, the kinematic model of a spacecraft can be expressed in this structure.
