Abstract:Concerning the problem of chaotic maneuvering control for sailing ship, a rectangular impulsive parametric perturbation control method based on the Melnikov function of controlled chaotic system was proposed through the non-linear ship steering model. The proposed method perturbed the chaotic system parameters by using rectangular pulse. Through solving the chaotic system's homoclinic orbit and constructing the Melnikov function of controlled chaotic system, the value range of the pulse parameters was fixed by mathematic method with reference to the simple zero boundary conditions of Melnikov function, and this method avoided blindly choosing the pulse parameters when controlling chaos. The experiments for the chaotic ship steering control show that, the proposed method can stabilize the chaotic system to periodic orbits, and amplitude of the stabilized system is only 8.5% of the original system. The experimental results demonstrate the effectiveness of the proposed method for the chaotic ship steering control.
