Supervisory Fault-Tolerant Control With Application to the IFATIS Two-Tanks Benchmark
Abstract
This paper reports the main ideas of a new technique for real-time fault-tolerant control (FTC) and demonstrates the effectiveness of this technique on a two-tanks process benchmark. The proposed technique relies on the operating data produced by the plant and on the control objective expressed quantitatively by a performance functional. The resulting control system architecture is of a supervisory type with the main feature that it achieves real-time fault tolerant control without on-line model-based fault detection and isolation (FDI) algorithms. The research activity has been performed within the framework of the research project Intelligent Fault Tolerant Control in Integrated Systems-IFATIS-funded by the European Union.
