Abstract

The invention discloses an electromagnetic docking control method and a device, which adopt an anomalous magnetic moment control plus one-time magnetic moment switching mode, wherein the electromagnetic docking control method includes the following steps: according to the magnetic induction intensity of a target electromagnetic device, the initial speed and initial magnetic moment of a tracking electromagnetic device and the initial distance between the barycenters of the target electromagnetic device and the tracking electromagnetic device, the initial mechanical energy of a docking system is calculated; according to the set switching speed and initial magnetic moment of the tracking electromagnetic device and the initial mechanical energy of the docking system, the switching distance, which corresponds to the switching speed, between the barycenters of the target electromagnetic device and the tracking electromagnetic device is calculated; according to the switching speed, the switching distance and the expected docking speed and expected docking distance of the tracking electromagnetic device, the switching magnetic moment of the tracking electromagnetic device is calculated; when the speed of the tracking electromagnetic device is changed into the switching speed, the electromagnetic moment of the tracking electromagnetic device is transformed into the switching magnetic moment. The invention solves the technical problem that the design of the conventional method is complex and the requirement for control design robustness is high.

Description

technical field [0001] The invention relates to the field of motion state control, in particular to an electromagnetic docking control method and device. Background technique [0002] On-orbit service technology represents the frontier and key direction of aerospace science development, and spacecraft rendezvous and docking is its key basic technology; at the same time, with the increase in the number of on-orbit spacecraft and the increase in the complexity of space missions, the demand for normalized Gradually become prominent. The spacecraft electromagnetic docking technology is to actively generate a magnetic field through the electromagnetic device on the star, and use the force / torque generated by the interaction between the magnetic fields to control the relative position / attitude between the spacecraft, so as to achieve the purpose of docking. Spacecraft electromagnetic docking technology provides a new docking method for normal on-orbit services, which can effectiv...
