Optimal calibration of ship degaussing system using stochastic particle swarm optimization;

In this paper,the integrated framework of visual interface software for ship degaussing is presented based on the software of LabWindows/CVI and MATLAB.

This paper discuss from the definition of the error for precision of ship degaussing current controlling installations and measuring install for the error to analyze system error of the measuring install.

The result of magnetic measuring experimentation is time-serial data-set,which could not been used to model warship magnetic field directly.

Magnet simulation is often used in calculating a vessel′s magnetic field,but the precision is affected by this positions of the magnet that often depend on human experience.

On the basis of analyzing the time frequency of a ship magnetic field by using short time Fourier transform, this paper discusses the time frequency distribution characteristics of the ship magnetic field.

This paper uses standardized correlation coefficients as the standards balacing the degree of simularity of multi channel signals On the basis of comparing measured data with simulated ones, it analyzes and sums up the degree of simularity of the passing characteristic curves of ship magnetic fields and hydro dynamic fields in unmerical quantities with the help of a new method .

For the need of testing of ship degaussing apparatus,the integrated test system based on virtual instrument technology has been designed.
