摘要：
According to the research of satellite magnetic characteristics and magnetic test, the model of satellite multi-magnetic dipole is established, the linear part and nonlinear parts are separated, The root mean square of the difference between the simulated value and the measured value is taken as the objective function, and the genetic algorithm is used to search the position of the multi-magnetic dipoles, at the same time, the fitness error between measurements and calculations is monitored so that when the object function reaches the optimum, the fitness error can meet the requirement. At last, the magnetic properties of the satellite in static state and electrified state are calculated, the result shows that the magnetic model obtained by adopting the method is high accurate and strong robust, the error of magnetic field and magnetic moment are both less than 5%. © 2020, Chinese Institute of Electronics.
