Many sophisticated approaches have been proposed for fault detection in dynamic systems using standard model representations. In this paper, redundancy relations for fault detection in systems represented by a generalized state space description are presented. Conditions for the existence of a redundancy relation and the simplest form this can take for the generalized system are obtained. The design of the redundancy relation in the presence of model uncertainties is also considered and conditions for the existence of a perfectly robust solution obtained. For cases where this does not exist a procedure is defined for calculating an optimally robust solution. A simulation of a three-shaft gas turbine is used to demonstrate the potential of the method.
