Research on control strategy of fin stabilizer for SWATH ships

WANG Min,HONG Chao (The 704 Research Institute of CSIC,Shanghai 200031,China)  
As a new type of high-performance vehicles,SWATH ship needs the fin stabilizer to control its motion state.In this paper,the vertical movement and lateral movement are decoupled based on the analysis of the motion equation of the SWATH ship.LQG optimal control technique is used to design and optimize the longitudinal motion control system according the state space model;variable parameter PID control algorithm is introduced to obtain the best anti-rolling effect in lateral motion control system;and the lateral movement and longitudinal movement control signals are processed dynamically.Through the simulation of a SWATH ship,the results show that the motion state is well controlled by using this control strategy.The fin stabilizer can effectively reduce the amplitude of the heave motion and pitch motion,and achieve good performance in roll reduction.
