Abstract :
A system for ROV actuator fault detection, diagnosis and accommodation through servo-amplifier monitoring and dedicated steady-state maneuvers has been designed on the basis of real data recorded during operating missions of Romeo, the ROV prototype developed by CNR-IAN. In particular, an actuator fault during sea operations of Romeo enabled the validation with real data of the developed system
