基于粒子群算法复合型磁靶结构参数优化调整

Optimization and adjustment of compound-type magnetic target's structure parameters based on particle swarm algorithm

通电线圈与永磁体复合型磁靶需要确定的结构参数类别较多,如果不采用有效的优化算法加以优化调整,很难通过经验设定来达到理想的磁场模拟精度。为了解决这一问题,提出了一种基于粒子群算法的复合型磁靶结构参数优化调整方法,该方法将电流参数、永磁体大小、区段间距、区段的长度同时进行优化,并通过一仿真算例验证了方法的有效性。

Since many structure parameters need to be determined for the compound-type magnetic target which is com-posed of coils and permanent magnets,it is impossible to get high precision if the parameters are not optimized and adjusted by an efficient optimization algorithm. In order to settle the problem,an optimization adjustment method of compound-type magnetic target’s structure parameters is proposed in this paper. With this method,the current parameters,magnet size,space between two sections and length of section were optimized. The validity of the method was verified by a simulation example.
