Fin stabilizer control based on backstepping and closed-loop gain shaping algorithms
Xianku Zhang · Journal of Dalian Maritime University · 2008
A nonlinear robust controller was designed by using backstepping and closed-loop gain shaping algorithms to improve the robustness of fin stabilizer controller.Under the same sea state,the nonlinear mathematical model was simulated by using Simulink of Matlab respectively under such different conditions as without roll stabilizer,controlled by fin stabilizer for the given velocity and half of the given velocity.The results show that the control strategy is effective to fin stabilizer control system,and the controller has strong robust stability.The algorithm suggested here has the advantages of simple design procedure and obvious physical sense.
