Experimental Fault Diagnosis in Systems Containing Finite Elements of Plate of Kirchoff by Using State Observers Methodology
(Iop Publishing Ltd, 2015-01-01)
This paper presents a methodology for detection and localization of faults by using state observers. State Observers can rebuild the states not measured or values from points of difficult access in the system. So faults ...
Robust controller implementation via state-derivative feedback in an active suspension system subjected to fault
(2013-12-01)
This work is focused on a practical implementation, of a robust controller designed by LMIs (Linear matrix inequalities), in an active suspension system manufactured by the Quanser®. For the implementation, it is supposed ...
