Abstract

A novel robust fault reconstruction approach is proposed for satellite attitude control systems (ACS) by proposing a learning unknown input observer (LUIO). Stability of LUIO and ultimately boundedness of dynamic fault deviation are proved using Lyapunov stability analysis. LUIO design problem can be solved effectively using MATLAB LMI toolbox. Finally, mathematical simulation on satellite closed-loop ACS demonstrates the effectiveness of the proposed approach.
