Intermediate observer based simultaneous estimation of system states and multiple faults
In this paper, an intermediate observer is proposed for simultaneously estimating the system state, actuator fault and sensor fault. The necessary and sufficient condition is given with respect to the existence of the designed observer. The observer gain

Reconstructing initial data using observers: error analysis of the semi-discrete and fully discrete approximations [PDF]
A new iterative algorithm for solving initial data inverse problems from partial observations has been recently proposed in Ramdani et al. (Automatica 46(10), 1616-1625, 2010 ).

Counteractive control against cyber-attack uncertainties on frequency regulation in the power system
In this study, an observer based control strategy is proposed for load frequency control (LFC) scheme against cyber-attack uncertainties. Most of research work focused on detection scheme or delay estimation scheme in presence of cyber-attack ...
