Identification for a Heading Autopilot of an Autonomous In-Scale Fast Ferry

The aim of this paper is to obtain a heading model for the purpose of control of an in-scale fast-ferry TF-120 physical model, including the dynamics and kinematics, using a remote experimentation platform for marine vehicles. The physical model is developed to be autonomous and is controlled remotely from a PC using WiFi communications. The identification and validation of the model dynamics is obtained with turning circle maneuverings. The tests with the autonomous in-scale physical model of the high-speed ship were carried out on the coastline of the Bay of Santander. The parametric model identified is used to design different classical control structures for a heading autopilot, and a simulation of this system is performed in Simulink.
