Simulation Research of Interference Magnetic Field Compensation Method on the Underwater Vehicle
Zhao Ta,Chenyu Wei,Zhouzhi Jian,Chengde Fu 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.4
It is one of the most difficult issues for underwater vehicle to accurately compensate the interference magnetic field elements in automatic navigation.The theory of geomagnetic navigation on underwater magnetic vehicle is complicated and the development of interference magnetic field compensation system is difficult, so in order to reserch the compensation method easily and effectively,it is a important way for using the finite element software on the computer to complete the modeling and simulation. In this paper, the space distribution characteristics of magnetic field around the vehicle are analyzed and the vector compensation mathematical model of interference magnetic field is established.At last, the feasibility of compensation method is testified by an united simulation system composed of Comsol Multiphysics and Matlab which is developed using the secondary development technology of software. The results show that the united simulation system can be convenient to complete the modeling and simulation of compensation method, not only accomplishing a magnetic field characteristic analysis and numerical calculation function, but also the simulation precision of compensation results is very high.
