A geometric approach to FDI diagnosis for input-affine nonlinear systems is briefly described and applied to a ship propulsion benchmark. The analysis method is used to examine the possibility of detecting and isolating predefined faults in the system. The considered faults cover sensor, actuator, and parameter faults.
Keywords: Geometric approach, input-affine nonlinear systems, fault detection, fault isolation, ship propulsion benchmark
