A dynamic degaussing system includes a magnetic field sensor for generating a sensor signal in response to a sensed magnetic field. The magnetic sensor is coupled to a controller that produces an output signal based on the sensor signal. The controller may include feedforward and feedback control loops. The output signal of the controller controls a magnetic field generator which generates a magnetic field so as to attenuate the sensed magnetic field. According to one aspect of the invention, a vessel is provided with a reduced magnetic signature and a control system for controlling magnetic fields about a podded electric motor. The control system employs feed-forward and feedback control in tandem. The control system may be dynamically adapted to changing physical characteristics of the motor. Control signals are generated in response to sensed or predicted magnetic fields internal to, or external to, the motor. The control inputs may be used to modify one or more motor driving currents, or to drive one or more magnetic field generators, so as to attenuate one or more magnetic field components generated by the motor.

11	Method for determining magnetisation and the field radiated by a ferromagnetic plate	US10343932	2003-05-14	US20030184284A1	2003-10-02	Olivier Chadebec; Jean-Louis Coulomb
The invention concerns the field of devices and appliances for measuring the intensity and the direction of the magnetic field emitted by a plate or a structure, such as for example a ship's hull and it particularly concerns a method for determining the magnetisation and the magnetic field radiated by a ferromagnetic plate using magnetic field sensors distributed along said plate and at known positions relative thereto. The invention is characterised in that it consists in: producing a mesh of said plate by clipping into elementary surfaces; producing a first modelling of the magnetic field associated with measurements and based on the produced surface meshing of the plate, on its thickness, on measurements, on co-ordinates of measurement points and on the excitation B0nullnull0H0; producing a second modelling of the physical behaviour of the material forming the plate based on the mesh, its thickness, the excitation, and the reversible permeability of the material; calculating the permanent and induced magnetisation levels of each of the elementary surfaces based on said first and second modelling and on the measurements performed by said magnetic field sensors; calculating the magnetic signature of the plate in every point based on said permanent and induced magnetisation levels of each of the elementary surfaces, the surface mesh produced on the plate, its thickness, measurements, co-ordinates of the calculation points and the excitation B0nullnull0H0.
12	Optimal degaussing using an evolution program	US09721998	2000-11-27	US06546349B1	2003-04-08	Paulo Bertell Tarr; Nevin D. Powell
An evolutionary program is used to calibrate a ship degaussing system with respect to one or more parameters relating to the ship's magnetic signature. Pursuant to the computer program, a mathematical vector lists electrical current values which correlate with the degaussing coils. A genetic algorithm is executed through a certain number of generational iterations in order to find a solution vector which will optimize the parameter(s). Every generational population has the same number of vectors. An initial population is randomly engendered, and successive populations are engendered through a biasedly random process wherein each vector has associated therewith a parenthood selection probability which is commensurate with its fitness. The offspring vectors are given birth to via crossover hybridization of parent vectors, and a small fraction of offspring vectors are randomly modified via mutation. The present invention is suitable for accomplishing optimization (e.g., minimization) of practically any parameter bearing relation to an entity's magnetic signature—i.e., not only of the magnetic signature itself but also of a variety of properties related thereto or derivative thereof. Depending on the inventive embodiment, a given genetic algorithmic program is capable of optimizing any number of diverse electromagnetic characteristics of any entity with respect to which a system of coils is being implemented.
