Satellite magnetic momenter multi-winding optimization design method based on genetic algorithm

Abstract

This invention discloses a multi-winding optimization design method for satellite magnetic torquers based on genetic algorithms, belonging to the field of aerospace electromechanical and attitude control actuator design technology. It addresses the challenges of inconsistent torquer diameters, sparse feasible solutions, and difficulties in coordinating parallel current sharing deviations under multiple constraints. The method activates and registers the rated magnetic moment and supply voltage within a unified computational domain, implements discrete set locking for the core material and enameled wire diameter, and establishes a parameter mapping table to limit single-winding, dual-winding, or multi-winding parallel channels. It registers the core geometry, number of winding layers, and rated current in variable and constant channels, introduces constraint source location, homotopy relaxation, and feasible projection, and incorporates dual-scale repair at the gene and process levels, as well as robust checks for temperature rise and batch differences. An optimization model with power consumption and weight as dual objectives is assembled, outputting the solution set and evaluation snapshot, and connecting manufacturing and calibration to complete backfilling and verification, achieving an integrated design that is low-power, low-weight, non-saturated, capable of current sharing, and manufacturable.
