Abstract

The invention provides an electromagnetic formation satellite attitude and track relative control method. The method comprises the following steps: 1, attitude dynamics equations are built; 2, according to the attitude dynamics equation in a linear form with quaternion representation built in the first step, an attitude dynamics equation in a body coordinate system and a rigid satellite dynamics equation, a satellite attitude control system feedback control law is designed and obtained; and 3, according to the feedback control law obtained in the second step, relative control is carried out on the electromagnetic formation satellite attitude and the track. The method of the invention has the advantages that the attitude dynamics equations, a relative motion dynamics equation and electromagnetic force and electromagnetic torque models are built, the designed satellite attitude control system feedback control law, a flywheel angular momentum magnetic unloading algorithm, a large angle attitude maneuver method, an electromagnetic formation flying satellite motion controller and a magnetic dipole control distribution method can have good working performance, and high-efficiency relative control on the electromagnetic formation satellite attitude and the track can be realized.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic formation satellite attitude and orbit relative control, in particular to an electromagnetic formation satellite attitude and orbit relative control method. Background technique [0002] Satellite Electromagnetic Formation Flight (EMFF) has many advantages such as no need for propellant and no contamination of optical sensors, and has received extensive attention in the past decade. The concept of electromagnetic formation flight can be applied to a variety of future missions, such as distributed spacecraft, astronomical interferometric analysis, and camera assembly. [0003] Professor Miller's team first proposed the concept of electromagnetic formation flight, and then MIT's Space Systems Laboratory began to study it, mainly studying the magnetic dipole model and conducting dynamic analysis, controller design and ground simulation tests , these studies have laid a solid foundation for t...
