Practical control of underactuated ships
WebApr 11, 2024 · In this paper, the tracking control problem of underactuated surface vessels with modeling uncertainties and unknown external disturbances is studied. The fuzzy logic system is applied to approximate the uncertainties in the model. A new disturbance observer with a learning factor is introduced to compensate external disturbances.
