Summary:This paper describes a novel adaptive backstepping sliding mode control (ABSMC) algorithm for a compact autonomous underwater vehicle subject to model errors and unknown disturbances. The closed-loop stability of the control system is demonstrated using the Lyapunov direct method. Simulation results are presented to show the effectiveness of the proposed control method. Furthermore, extensive experimental results show that the proposed algorithm outperforms sliding mode controllers (SMC) in terms of control performance and adaptability to changing system state.
