Path following control for underactuated AUV based on feedback gain backstepping

Original scientific paper In order to achieve path following control for the underactuated AUV in the horizontal plane, we propose that the tracking error equations are established based on virtual target and a novel backstepping method is designed based on Lyapunov stability theorem and feedback gain technique. The nonlinear terms in the error dynamic model can be compensated by adjusting feedback gain of the controller, which can avoid the high-order derivative of the virtual control variable in common backstepping and reduce the complexity of controller and improve adjustability of the controller parameters. Finally, simulation experiments are carried out on WL-II under actuated AUV. The results show that the controller can follow the expected horizontal path precisely, and has theoretical and practical value.
