摘要
永磁定位技术因其无需外接激励电路和适用于小空间非透明环境等优点,在生物医疗和湍流检测等领域备受关注。该技术利用空间反演算法从永磁体的磁场信息中提取位姿信息,从而实现永磁体的定位。为获得更精确的位姿信息,需采用更有效可靠的空间反演算法对磁场信息进行反演运算。因此,该文提出一种基于差分进化算法的空间反演算法,并通过设计对比实验研究空间反演算法对永磁体定位准确度和速度的影响。结果表明,该文提出的空间反演算法具有更高的定位和定向精度以及更快的迭代速度。平均定位误差为(2.49±1.49)mm,平均定向误差为(1.48±0.61)mm,平均迭代次数为78.4次。
Permanent magnet positioning technology has attracted considerable attention in fields such as biomedicine and turbulence detection due to its advantages of not requiring external excitation circuits and being suitable for small space non-transparent environments.This technology utilizes spatial inversion algorithms to extract positional information from the magnetic field of the permanent magnet,thereby achieving localization of the permanent magnet.In order to obtain more accurate positional information,it is necessary to employ more effective and reliable spatial inversion algorithms for the inversion computation of the magnetic field information.Therefore,this paper proposes a spatial inversion algorithm based on differential evolution algorithm and investigates the influence of the spatial inversion algorithm on the accuracy and speed of permanent magnet positioning through designed comparative experiments.The experimental results show that the proposed spatial inversion algorithm exhibits higher positioning and directional accuracy as well as faster iteration speed.The average positioning error is(2.49±1.49)mm,the average directional error is(1.48±0.61)mm,and the average number of iterations is 78.4 times.
