Disturbance Observer-Based H∞Control for Flexible Spacecraft Systems Under Deception Attacks

A disturbance observer-based $H_{\infty}$ composite control method under disturbances and deception attacks is addressed in this paper. Firstly, the control model is constructed. Secondly, a disturbance observer-based $H_{\infty}$ composite controller via linear matrix inequality (LMI) is developed based on a Lyapunov function. Finally, we present simulations to verify the validity of design method.
