A low-complexity prescribed performance control (LCPPC) method on basis of the prescribed performance control theory is proposed in this paper for a chasing spacecraft approaching and tracking a non-cooperative target spacecraft. Any information of the system parameters, including the mass and inertia matrix of the chasing and target spacecraft, is unnecessary. Moreover, the transient performance as well as the steady performance of the system can be prescribed and guaranteed despite the external disturbance, parameter uncertainties and unknown non-cooperative target’s maneuver. The simulation results show that the high precision real-time control is realized for approaching and tracking the non-cooperative target in a line-of-sight coordinate system.
