Disturbance Observer-Based Model Predictive Control for an Unmanned Underwater Vehicle
Journal of Marine Science and Engineering, 2023 This work addresses the motion control problem for a 4-degree-of-freedom unmanned underwater vehicle (UUV) in the presence of nonlinear dynamics, parametric uncertainties, system constraints, and time-varying external disturbances. A disturbance observer-based control scheme is proposed, which is structured around the model predictive control (MPC ...
