The invention discloses a method for determining the reconfigurability of a satellite control system. The method comprises the following steps of: (1) constructing a satellite control system function tree and connecting the different levels of the function tree by means of AND Gate or OR Gate according to the function implementation mode of the satellite control system; (2) according to the AND / OR relationship between different levels of the function tree, determining the cut-set family C of the function tree by using the descending method or the ascending method, wherein the elements of the cut-set family are cut-sets and the cut-sets are component sets for implementing the functions of the satellite control system; (3) performing absorption treatment on the cut-set family C determined in the step (2) to obtain the minimum cut-set family Cmin of the function tree, wherein the elements of the minimum cut-set family Cmin are minimum cut-sets cmin and the minimum cut-sets cmini are the sets of least components required for implementing the functions of the satellite control system; (4) performing failure mode effect analysis (FMEA) on the satellite control system to determine the failure mode, failure occurrence probability and failure severity of the satellite control system; (5) determining the reconfigurable degree (Gamma-i) of the failure mode i; and (6) determining the reconfigurable rate of the satellite control system.
