摘要

To solve the straight-path following problem of underactuated surface ships with parametric uncertainties and external disturbances,a dynamic nonlinear sliding mode control method is presented.Integrated with simple increment feedback,the controller is proved to stabilize the underactnated ship's orientation and cross-track without uncertainty estimation.Problems of states constraints and actuator saturation are also solved.Numerical simulation results on a full nonlinear hydrodynamic model of a training ship are presented to validate the invariability and excellent robustness of the proposed controller.
