The invention provides an aircraft cabin door control system and control method. The control system is characterized in that a three-phase signal input end of a three-phase asynchronous motor is connected with a first power supply; each control module of the plurality of control modules is used for receiving at least one control signal input from the outside and performing logic processing on the received control signal; the plurality of control switches are connected in series on a power supply circuit of the three-phase asynchronous motor and comprise a control switch for controlling the three-phase asynchronous motor to switch forward and reverse rotation and a control switch for controlling the three-phase asynchronous motor to switch winding wiring, and the control end of each control switch is connected with the second power supply and the corresponding control module. And the control module is used for controlling the three-phase asynchronous motor to open, close or stop the cabin door according to the
