A NEW SHIP CONTROL DESIGN CRITERION FOR IMPROVING HEAVY WEATHER STEERING
The paper presents the results of work on formulating a new steering design criterion based on minimizing the added resistance caused by rudder activity and hull drag of inertial origins caused by periodic yawing of a ship in a seaway. Performance criteria to which the steering control system can be designed are developed. Ship response with a conventional controller is compared to that with a new controller design based on minimizing propulsive losses and in the cases shown, significant reduction of resistance is achieved.
