Nonlinear Robust Stabilization of Ship Roll by Convex Optimization

Dear Editor, This letter presents a nonlinear robust controller design method for ship roll stabilization by combining the dual of Lyapunov's stability theorem with the sum of squares (SOS) technique. Varying initial metacentric height and ship speed are regarded as uncertainties, sea waves are...

Summary:Dear Editor, This letter presents a nonlinear robust controller design method for ship roll stabilization by combining the dual of Lyapunov's stability theorem with the sum of squares (SOS) technique. Varying initial metacentric height and ship speed are regarded as uncertainties, sea waves are considered as external disturbances, and then the robust nonlinear controller is designed. Taking a container ship as an example, simulations are performed to verify the effectiveness of the proposed design scheme.
