WebThis paper describes the application of model reference adaptive control (MRAS) to automatic steering of ships. The main advantages in this case are the simplified controller adjustment which yields safer operation and the decreased fuel cost. WebThis paper presents an effective adaptive autopilot for ships, based on model reference adaptive system (MRAS) and self tuning regulator (STR) control theories. Simulation in various disturbance conditions shows that the autopilot has several notable advantages: high course turning speed, high accuracy of course keeping, low swing of ship bow, …
