A STUDY ON OPTIMIZATION OF SHIP MANOEUVRING BY OPTIMAL CONTROL THEORY

The optimal control problem for ship handling is discussed. The control of ship manoeuvring motion is mathematically formulated as a two-points boundary value problem because both initial and final status values are given and the control inputs are sought to satisfy these two terminal conditions. Some nonlinear optimisation techniques are shown. Using a small training ships, some sea trial tests were carried out to confirm the performance of the proposed control method. Using optimal control references given by the method presented instead of the step function as a further application, it is shown that the step response of the conventional feedback control system can be improved.
