%X A special redefinition output variable,which makes the relative degree of the system be zero,is presented for the ship's straight-line tracking nonlinear system.At the same time, a class of state feedback control laws are developed.In this pa- per,through stability analysis based on a novel Lyapunov func- tion and Lyapunov's direct method,the sufficient conditions of global asymptotical stability and the deductions are given.The results of numerical simulation and experiments on a simulator show the validity of the sufficient conditions.
