【Abstract】 With the development of warship degaussing technology, the number of degaussing coils gets more and more, and conventional methods of calibrating degaussing systems are more and more difficult to implement. To solve this problem, an improved particle swarm algorithm is proposed, which adopts the search strategy of poly-population particle to compress search space to improve the probability of searching global optimization solution. The simulation results show that this algorithm has more advantages than others in terms of minimizing the root mean square and peak of the warship degaussing magnetic field signature. In addition, this algorithm has many excellences such as intuitional algorithm, simple program, fast computation speed and high global searching probability, which make it easy to collaborate multi-computer and be applied to real projects.更多还原
