Model reference adaptive autopilots for ships
Web1 dec. 2003 · A novel model reference adaptive robust fuzzy control algorithm is presented for ship steering autopilot, which is an uncertain nonlinear system. In the proposed … 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, …

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. After discussion of the mathematical models of process and disturbances, criteria for optimal steering are defined.
