Abstract
We propose a method for failure detection in complex multi-variable multi-time scale systems. It consists in the introduction of redundancies in the global system, with overlapping transformations on the slow variables. This decomposition applied simultaneously with the singular perturbations method allows to build composite decentralised observers and to identify malfunctioning sensors. A comparison is made on an example between failure detection results obtained with full-rank composite observers and those deduced from the design of slow local subobservers.
