Design of a Complete FDI System based on a Performance Index With Application to an Automotive Engine
Assuming residual generators are already available, there are still
several choices to be made when a complete FDI system is to be
designed. This is a time-consuming engineering work so for this purpose, a
systematic procedure is proposed. The procedure is phrased as an
optimization problem. The goal is to minimize a new probability based
performance index, which is derived from measurements on the real
process. To increase the robustness of the FDI system, a \textit{don't
care} option is introduced in the residual structure. The procedure
is successfully applied to the problem of FDI design for the
air intake system of an SI-engine.
