摘要
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 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. Copyright (C) 1998 IFAC.
