Abstract :
In this paper the idea of inversion-based direct input reconstruction for robust detection, separation and estimation of multiple simultaneous faults in the presence of persistent disturbances in linear dynamical systems is presented. In particular, it is shown how in a specific filtering structure a residual generator, relying on the inverse representation of the system, by means of estimation of the inverse dynamics can be designed providing robust fault decoupling. The development of the method and its applicability to earlier not solvable problems is demonstrated based on an aircraft monitoring application example.
