Abstract

The dynamics and control of sway and yaw motions of a ship with combined fin-rudder control system are discussed. In this system, a multivariable controller is used to take into account sway, roll and yaw motions induced by deflections of rudder as well as stabilizing fin for course-keeping and roll stabilization of a ship in quartering seas. A simulation study is carried out to make the comparison between fin, rudder and conbined fin-rudder control systems. In addition, self-running model tests in still water are carried out to make sure if the simulation results are in good agreement with the experimental results.
