Abstract: This paper researches on the problem of path-following control of underactuated autonomous underwater vehicles (AUV). In SerretFrenet frame, a pathfollowing error dynamics, corresponding to a virtual target AUV, was constructed. Building on the error dynamics and combining with the vehicle’s dynamics, a nonlinear controller based on Lyapunov stable theory and backstepping techniques was developed. The resulting nonlinear feedback control law yields convergence of the path-following error trajectory to zero. The simulation results illustrate the performance of the control system proposed.
