A model-based approach for fault-tolerant control

A model-based controller architecture for fault-tolerant control (FTC) is presented in this paper. The controller architecture is based on the Youla-Jabr-Bongiorno-Kucera (YJBK) parameterization. The FTC architecture consists of two central parts, fault detection and isolation (FDI) part and a controller reconfiguration part. The theoretical basis for the architecture will be given followed by an investigation of the single parts in the architecture. At last, system interconnection will be considered with respect to the described controller architecture.
