The invention discloses a non-cooperative spacecraft electromagnetic capture method based on multi-satellite serial release. The method comprises the following steps: S1, a main spacecraft performs serial release to capture satellites; s2, capturing a plurality of feature points of an area where the satellite flies to find the non-cooperative spacecraft; s3, the main spacecraft calculates the optimal feature point of each region; s4, capturing each optimal feature point of satellite flying, and completing successive capturing at the point in an electromagnetic docking mode to form a connecting pipe assembly; s5, performing inertial parameter identification on the connecting pipe assembly, and attributing attitude dynamics system uncertain items caused by identification errors to comprehensive disturbance to form a parameter identification enhancement effect; and S6, designing a controller based on an interference observer, and sending an instruction to each capture satellite execution mechanism through a torque distribution principle, thereby realizing electromagnetic capture takeover of the non-cooperative spacecraft. The method can overcome the defects that the single-satellite capturing capability is weak and rigid collision with the non-cooperative spacecraft is easy to occur, and can cope with various complex non-cooperative spacecraft capturing tasks.
