The application of a new fault-tolerant control methodology to a well-known benchmark is considered. The benchmark is the model of a propulsion system for a marine vehicle developed by the Control Engineering Department of Aalborg University. After a brief description of the system, a fault analysis is carried out leading to a set of possible faults and remedial actions. Then the fault detection and identification method, and the reconfiguration algorithm are described. Simulations on the model illustrate the performance of the fault tolerant system for some selected fault scenarios. which allows perfect isolation of the three possible faults pro-posed in the benchmark. The information provided by the FDI are then used to develop a control reconfiguration structure in order to achieve a fault tolerant control system, able to preserve pre-specified performance also in presence of faulty situation. Simulation results show the effectiveness of the control structure presented.
