Fault detection schemes to support integrated aircraft control must account for the effects of model errors. The underlying theory developed here is similar to recent advances in robust control and results in analytic tools that quantify the tradeoffs between model error and sensor failures. In particular, a detection scheme, which naturally arises from the theory, includes a filter whose purpose is to account for reference command transients and noise levels in accordance with anticipated model error. Also, the theory identifies the minimum detectable failure in a given set of admissible failures. This minimum is a function of model errors, noise levels, and the class of reference commands. Calculation of this minimum is an essential step in a practical FDIA synthesis approach.
