Description

Refrigerator and control method thereof Cross Reference to Related Applications The present application claims the benefit of priority from korean patent application No. 10-2020-0092413 filed at korean intellectual property office on 24 th 7/2020, the disclosure of which is incorporated herein by reference in its entirety. Technical Field The present disclosure relates to a refrigerator and a control method thereof. More particularly, the present disclosure relates to a refrigerator automatically opening and closing a plurality of doors and a control method thereof. Background A refrigerator is an electronic device (or a home appliance) for storing edible and drinkable foods refrigerated or frozen by a refrigerating cycle using a refrigerant. In addition to foods, the refrigerator may store medicines, alcoholic beverages, or cosmetics. In the related art, a user typically opens and closes a door of a refrigerator manually. However, when a user holds a thick plate on his/her hand, the user often cannot open the door of the refrigerator by himself/herself, and thus, an automatic opening function of the door of the refrigerator is required. Accordingly, there is an increasing demand for users of technologies related to refrigerators having doors that are automatically opened and closed and for research and development thereof. Meanwhile, in order to automatically open and close the door of the refrigerator, a motor is required to be provided to power so that the door rotates. In general, in order to open the door when the door is closed, a high power is required due to a pressure difference between the inside and the outside of the refrigerating chamber, and thus, the motor needs to be rotated rapidly. In order to open a plurality of doors of a refrigerator, a plurality of motors need to be driven, and thus there is a problem in that a device for supplying high power to the plurality of motors needs to be provided. The above information is presented merely as background information to aid in the understanding of the present disclosure. No determination is made as to whether any of the above is applicable as prior art to the present disclosure, and no assertion is made. Disclosure of Invention Technical problem Aspects of the present disclosure address at least the above problems and/or disadvantages and provide at least the advantages described below. Accordingly, it is an aspect of the present disclosure to provide a refrigerator and a control method thereof that effectively open and close a door by controlling the sequence and time of the opening and closing of a plurality of doors. Additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the presented embodiments. Technical proposal According to one aspect of the present disclosure, a refrigerator is provided. The refrigerator includes a main body including a first door and a second door, a first motor for opening the first door and a second motor for opening the second door, and a processor configured to start driving the first motor to open the first door based on an acquisition of a user command for opening the door, and start driving the second motor to open the second door after a first time from a time when the first motor has started to be driven. The first time may be a time when the magnitude of the surge current applied to the first motor by starting the driving of the first motor becomes a value smaller than the threshold value. The processor may be further configured to drive the first motor with an operating current having a magnitude less than the inrush current until the first door opens at a threshold angle after the first time. The second door may be combined with a rotating railing. The processor may be further configured to start driving the second motor to close the second door based on a lapse of a first threshold time from a time when the operation of opening the first door and the second door is completed, and start driving the first motor to close the first door after a second time from a time when the second motor has started to be driven to close the second door. The second time may be a time after generating a back electromotive force on the second motor by starting driving of the second motor to close the second gate and before an increase in magnitude of the surge current flowing into the second motor. The processor may be further configured to control Revolutions Per Minute (RPM) of the first motor and the second motor based on the first door and the second door being opened at the threshold angle such that the opening operations of the first door and the second door are completed simultaneously. The processor may be further configured to control RPM of the first motor and the second motor based on at least one of a weight of each of the first door and the second door and a point in time when the door is opened at the thresh
