We proposed a nonlinear control method for trajectory tracking of underactuated surface ship. The nonlinear hydrodynamic damp and sway velocity are included in the ship model, which can stand for high speed and low speed of the ship. In kinematics loop the reference yaw angle and the reference speed are given. The nonlinear controller is designed in dynamics loop to make the error variables asymptotically stable. The stability of the closed-loop system is analyzed by using Lyapunov theory. Simulation results illustrate the effectiveness of the proposed control method.

2008 International Workshop on Chaos-Fractals Theories and Applications & the 9th International Conference for Young Computer Scientists

作者： TianKai Sun1, XiaoGen Shao1, XingYuan Wang2 1.Xuzhou Institute of Technology Xuzhou, 221008, china 2.school of electronic & information engineering, Dalian University of Technology, Dalian 116024, china

A novel binary image digital watermarking algorithm based on DWT and chaotic encryption is proposed. The proposed scheme utilized the Logistic chaotic sequences and generalized cat mapping to scramble the watermarks, so that the security of embedding watermarks was enhanced. The improved binary method was utilized and watermarks are embedded to the low frequency coefficients of deep wavelet domain. The original image is not required for detecting the watermarks .Using the statistical method the veracity is improved. The experimental results show that the watermark is robust against the cut attack, salt-pepper noise attack, JPEG and et al.
