The invention discloses a
spacecraft formation tracking control method, device, equipment and medium, relates to the technical field of
spacecraft control, is applied to a controller in a target
spacecraft formation, and comprises the steps: determining each topological neighbor set according to the interaction
connectivity of each spacecraft in the target
spacecraft formation, inputting a potential collision set in the topological neighbor set into a preset formula constructed based on an artificial potential function, and inputting the output collision avoidance control information into a preset formula constructed based on
controller design parameters to obtain an initial formation tracking
control signal; the design parameters are designed based on an immersion and invariant
algorithm and a preset
performance function;
processing the initial formation tracking
control signal based on an event triggering mechanism so as to obtain a
control error input
signal by using the obtained final formation tracking
control signal; and when the
control error input
signal meets a preset triggering condition, the collision avoidance control information is transmitted to an
actuator of each spacecraft, and tracking control is realized. And accurate tracking and low-
cost control are carried out on the
spacecraft formation.
