For a nonlinear course keeping system for ships,a kind of nonlinear robust PID is presented,which is based on an exact feedback linearization and a closed-loop gain shaping algorithm.

The nonlinear mathematical model was linearized through exact feedback linearization,then a robust exact feedback linearizing controller was designed using closed-loop gain shaping algorithm,and applied to course-keeping of autopilot for ships.

Then, based on the elastic hammer model, the numerical simulations demonstrate that the performance of the method is similar to that of the exact feedback linearization method in the transient process of a three-phase short circuit fault and load disturbances, and the method is more robust against m.

It is forwarded the new control method with accurate feedback linearization based on differential geometry.
