  • Abstract
    A ship course-keeping control system is formulated as a nonlinear H∞ control problem. In order to construct a nonlinear H ∞ controller to solve the problem, it is essential to find a solution for the Hamilton-Jacobi equation (HJE). A modified successive algorithm is proposed to obtain an approximate solution of the HJE and then a nonlinear H∞ controller is constructed. Simulations of the closed-loop ship motion responses are provided to illustrate the performance and robustness of the nonlinear H ∞ controller
