[0098] according to figure 2 The force model of the current-carrying coil in the magnetic field, the torque satisfies the formula (1)

[0099]

[0100]

[0101] is the magnetic moment of the current-carrying coil, is the coil area vector, I is the current through the coil, is the magnetic intensity.

[0102] The magnetic field generated by the air-core coil is small, which cannot meet the index requirements of the satellite attitude control system. Therefore, the magnetic field generated by the energized coil must be increased through the magnetization of the magnetic material. When the magnetic core is inserted into the current-carrying coil, the internal magnetic induction intensity is significantly enhanced, and the generated magnetic moment is also significantly increased. The magnetic induction intensity and magnetic moment can be expressed by formula (3) and formula (4)

Abstract

The invention relates to a multi-objective design method for a micro-star magnetic torquer. The method is based on a micro-star magnetic torquer multi-objective design system. The system comprises a parameter input unit (11), a magnetic core and winding database (12), a design unit (13), a screening unit (14) and a file output unit (15). The design unit (13) performs analysis and calculation according to related design information of the parameter input unit (11), the magnetic core and the magnetic torquer of the winding database (12) to obtain all feasible design schemes; the screening unit (14) screens an optimized design scheme from all feasible design schemes according to a given screening condition, and extracts an optimal design scheme in a screening condition range at the same time.The obtained result is output and displayed through a file output unit (15).

Description

technical field [0001] The invention relates to the technical field of parameter design of a magnetic torquer, and relates to a multi-objective design method for a tiny MSI magnetic torquer. Background technique [0002] The magnetic torquer is one of the main executive parts of the attitude control of the near-Earth small satellite. It is composed of a soft magnetic material core wound with a coil. In the design of the magnetic torque device, it is necessary to determine reasonable magnetic core and winding parameters. According to the given design requirements, the traditional method first roughly selects the magnetic core, and calculates and deduces some constraints on the winding according to the selected magnetic core parameters. Then select the appropriate winding according to the constraints of the winding. There is a certain blindness and experience in the selection of this core and winding. Due to the diversity of core and winding specifications, there are also div...
