A control method of a laundry treatment apparatus comprising a tub configured to provide a space for storing water, a tub introduction port on an upper surface of the tub, a drum provided in the tub for storing laundry, a stator configured to generate a rotating field when current is supplied to the stator, a rotor configured to be rotated by the rotating field generated by the stator, and a rotary shaft extending through the tub for connecting the rotor to the drum, the control method comprising: a laundry weight measurement step for rotating the drum at a predetermined first number of rotations to measure a weight of the laundry stored in the drum by measuring a current supplied to the stator; an unbalance measurement step for rotating the drum at a predetermined second number of rotations to determine a magnitude of a dynamic unbalance of the drum by measuring a current supplied to the stator; an acceleration step for accelerating the drum to a target number of rotations, which is greater than the first number of rotations and the second number of rotations, when the magnitude of the dynamic unbalance measured at the unbalance measurement step is less than a predetermined reference value; a first interruption step for interrupting a rotation of the drum when a variation per unit time of current supplied to the stator during execution of the acceleration step is equal to or greater than a predetermined reference variation; a laundry weight remeasurement step for rotating the drum at the first number of rotations to determine the weight of the laundry stored in the drum by measuring a current supplied to the stator; and a second interruption step for interrupting the rotation of the drum when a deviation between a laundry weight measured at the laundry weight remeasurement step and the laundry weight measured at the laundry weight measurement step is equal to or greater than a predetermined reference deviation. a laundry weight measurement step for rotating the drum at a predetermined first number of rotations to measure a weight of the laundry stored in the drum by measuring a current supplied to the stator; an unbalance measurement step for rotating the drum at a predetermined second number of rotations to determine a magnitude of a dynamic unbalance of the drum by measuring a current supplied to the stator; an acceleration step for accelerating the drum to a target number of rotations, which is greater than the first number of rotations and the second number of rotations, when the magnitude of the dynamic unbalance measured at the unbalance measurement step is less than a predetermined reference value; a first interruption step for interrupting a rotation of the drum when a variation per unit time of current supplied to the stator during execution of the acceleration step is equal to or greater than a predetermined reference variation; a laundry weight remeasurement step for rotating the drum at the first number of rotations to determine the weight of the laundry stored in the drum by measuring a current supplied to the stator; and a second interruption step for interrupting the rotation of the drum when a deviation between a laundry weight measured at the laundry weight remeasurement step and the laundry weight measured at the laundry weight measurement step is equal to or greater than a predetermined reference deviation.
