Abstract :
The purpose of this study is to improve a mooring system with Controllable Pitch Propeller (CPP). Because of the slip of propeller, velocity response of CPP has time delay. In this study, the ship´s propelling force with the CPP´s angle was identified on an actual ship and delay time was observed by analyzing the data of propelling force. Then the CPP angle is controlled by using Generalized Minimum Variance Control (GMVC) to obtain better performance for the mooring system.
