英文摘要
      To deal with the speed-jump in the conventional backsteepping tracking control for underwater vehicles, we propose a hybrid control combining the backstepping and the sliding-mode control based on the biological inspired model. Because of the smoothness and boundedness of the output from the bio-inspired model, this control produces a gradually varying reference tracking-speed for the underwater vehicles instead of a jumping reference tracking-speed which cannot be followed by the propeller thrust of underwater vehicles. An adaptive sliding-mode control algorithm is applied to generate the tracking control law which ensures the robust performance in the presence of underwater disturbance and model uncertainties to achieve the stable and accurate trajectory-tracking. The stability of the proposed method can be proved by Lyapunov theory. Finally, this control has been applied to simulate the horizontal discrete trajectory trackingcontrol on FALCON open-frame underwater vehicle. Experiment results validate the effectiveness of the proposed control method.
