A novel fault reconstruction approach to satellite attitude control system via learning unknown input observer and H∞ techniques

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… (More)
