Non-contact magnetic measurement method is an effective way to study the air arc behavior experimentally. One of the crucial techniques is to solve the electromagnetic field reverse problem. The paper is devoted to investigate the different algorithms for this kind of reverse problem preliminarily, including preconditioned conjugate gradient method, penalty
function method and genetic algorithm. The feasibility of each algorithm is analyzed. It shows that the preconditioned conjugate gradient method is valid only for less arc segments, the estimation accuracy of the penalty function method is depended on the setting of the initial values to much extent, and the convergence of genetics algorithm should be studied further to more segments of arc current. |
