Development of Criteria for Automatic Steering.
Abstract
The effect of added resistance due to steering on a high-speed containership is propulsion reduction. Limitation on the propulsion losses can be achieved by a properly designed controller, which minimizes the rudder activity as well as providing desired overseas heading. A computer program, simulating a cascade configuration of the SL-7 high-speed containership along with a specific controller was coupled to a function minimization subroutine as well as a sea state generator subroutine in order to minimize criterion. The entire model was tested for a fixed speed, several encounter frequencies, several encounter angles in calm waters and in a seaway as well. Originator-supplied keywords: Regular seas, Irregular seas, Controller design, Encounter frequency, Encounter angle, Yaw, Rudder, BOXPLX subroutine.
