The invention discloses a multi-redundancy landing gear electric retraction controller, and aims to provide a controller with light weight, small size, good reliability and strong environmental adaptability. According to the technical scheme, a main control CPU combination module is connected with a standby control CPU combination module and is correspondingly connected with a main control drivingcombination module and a standby control driving combination module through forward rotation and reverse rotation, output enabling, start setting 1, motor speed regulation, current sampling and hardware cut-off control lines respectively; the main control CPU combination module and the standby control CUP combination module are connected with a switching module and a standby switching module through driving main and standby control switching signal lines and a motor driving control line; the main and standby switching modules are connected with a landing gear motor unit through the motor driving signal line; the main control CPU combination module receives a landing gear retraction command, controls logic processing and sends a motor control command; the main control driving combinationmodule and the standby control driving combination module receive motor control commands of the main control CPU combination module and standby control CPU combination module and a motor Hall sensor signal.
