Motion Control of Ocean Vehicles using Online Trajectory Planning based on B-spline Interpolation and Model Predictive Control

Abstract

In this paper, we discuss the motion control of underactuated ocean vehicles by using trajectory planning and trajectory tracking control. Important factors which greatly affect the control performance are their model errors, disturbances, obstacles, and actuator constraints. To solve these problems, we attempt to apply the B-spline interpolation method for trajectory planning and model predictive control for trajectory tracking control. We propose a new online control algorithm for the underactuated ocean vehicles and evaluate the performance of the proposed algorithm by numerical case studies.
