摘要
提出一种解决静态磁场反演问题的新方法。目的在于通过测量空气中磁场,建立起铁磁性外壳物体的磁化模型,计算出某个位置因无法布放传感器的磁场。然而该方法会产生一个病态系统,必须采用数学优化方法处理该系统。本文通过增加物理信息,不仅获得了可靠的解决办法,而且大大减少了传感器的数量。此外,通过船模实测数据验证了该方法,具备一定的前景价值。
In this paper,we propose a new approach to solve the magnetostatic inverse problem. The goal of the work is,from measurements of the magnetic field in the air,to rebuild a model for the magnetization of a ferromagnetic shell structure. It＇s then possible to calculate the field where sensors can＇t be placed. This problem is usually ill posed, it＇s then necessary to use mathematical regularizations. These technics are based upon the injection of knowledge about the mathematical behavior of the solution. We prefered to add physical information. This solution allows us to get a faithful solution and to reduce method has been tested on a mock-up with real measurements significantly the number of sensors. Moreover, our and led to very promising results
