We propose a methodology to detect and isolate link failures in a weighted and directed network of identical multi-input multioutput linear time-invariant (LTI) systems when only the output responses of a subset of nodes are available. Our method is based on the observation of jump discontinuities in the output derivatives, which can be explicitly related to the occurrence of link failures. The order of the derivative at which the jump is observed is given by r(d+1), where r is the relative… CONTINUE READING
