摘要: |
The effect of added resistance due to steering on a highspeed 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 e function minimization subroutine As well as a sea state generator subroutine in order to Minimize a performance 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. |
