COMPARISON OF DIFFERENT MATHEMATICAL MODELS OF SHIPS AND THEIR CONTROL: EXPERIMENTAL RESULTS
Several mathematical models representing the dynamic behavior of the ship have been proposed and are utilized, both for studying the response to the sea disturbances, and for obtaining the response to the rudder actions. This paper considers such models based on recent studies. It points out the basic importance of the parameters identification; in fact the processes are remarkably variable for a given ship, in connection with the sea conditions, the load of the ship, etc. (even if they are slowly variable, so that it is possible to consider them quasi-stationary processes). The conclusion is drawn that also very simple models are acceptable, of the 3rd or even of the 2nd order, on condition that they be based on realistic parameters obtained by means of suitable measurements during the operation of the ship.
