The invention provides a satellite constellation electric propulsion deorbit control method and system, and relates to the technical field of spacecraft orbit design and control, and the method comprises the steps: S1, selecting the feature point height of a deorbit orbit according to the deorbit task requirement, and calculating the semi-major axis and eccentricity rate of a target orbit; s2, adjusting the semi-major axis of the track, and continuously igniting along the tangential direction until the semi-major axis is reduced to a target value; s3, the eccentricity rate of the track is adjusted, the whole track is ignited, and ignition is conducted in the direction perpendicular to the arch line till the eccentricity rate meets the target value; and S4, ignition is carried out at the orbit feature points until the perigee height and the apogee height meet the deorbit requirement. According to the method, rapid evaluation and optimization of the deorbital orbit parameter set can be realized; and by adopting a strategy of stage ignition under different coordinate systems, the coupling of the semi-major axis and the eccentricity is reduced, and the complexity of an actual task deorbit scheme is simplified.
