Abstract :
This paper studies fault tolerant control (FTC) for the ship-propulsion benchmark problem. Fault detection and isolation (FDI) methods have been presented during the past decade. Often, observer schemes were applied for linear or linearized systems. In this paper the FDI problem is solved using nonlinear observers, so that the system does not have to be linearized. The nonlinear observer is applied to a subsystem of the ship propulsion benchmark problem.
