A method for controlling a laundry machine to execute a refreshing course for removal or reduction of creases formed at laundry through supply of steam to the laundry, comprising: a course selection operation of selecting one of a plurality of courses ; a steam water supply operation (S2) of supplying water from an external water supply source to an interior of a tub up to a water level for generation of steam while preventing the water to pass through a drum , when the refreshing course is selected in the course selection operation; a steaming operation (S3) of heating the water by driving a washing heater provided at the tub , thereby generating steam from the water supplied to the water level for generation of steam; and a refreshing operation (S4) of refreshing the laundry after execution of the steaming operation (S3) by executing a tumbling driving operation to tumble the laundry within the drum in accordance with rotation of the drum ; characterized by during the refreshing operation (S4) alternately executing the stumbling driving operation and a spin driving operation to rotate the laundry within the drum in close contact with an inner surface of the drum together with the drum in accordance with rotation of the drum , wherein the rotation speed at the spin driving operation is higher than the rotation speed at the tumbling driving operation and lower than the rotation speed of spin-drying driving operation for removal of moisture through centrifugal force, wherein a time taken for the tumbling driving operation is longer than a time taken for the spin driving operation in the refreshing operation and a drum driving cycle including the tumbling driving operation and the spin driving operation is repeated multiple times in the refreshing operation. a course selection operation of selecting one of a plurality of courses ; a steam water supply operation (S2) of supplying water from an external water supply source to an interior of a tub up to a water level for generation of steam while preventing the water to pass through a drum , when the refreshing course is selected in the course selection operation; a steaming operation (S3) of heating the water by driving a washing heater provided at the tub , thereby generating steam from the water supplied to the water level for generation of steam; and a refreshing operation (S4) of refreshing the laundry after execution of the steaming operation (S3) by executing a tumbling driving operation to tumble the laundry within the drum in accordance with rotation of the drum ; characterized by during the refreshing operation (S4) alternately executing the stumbling driving operation and a spin driving operation to rotate the laundry within the drum in close contact with an inner surface of the drum together with the drum in accordance with rotation of the drum , wherein the rotation speed at the spin driving operation is higher than the rotation speed at the tumbling driving operation and lower than the rotation speed of spin-drying driving operation for removal of moisture through centrifugal force, wherein a time taken for the tumbling driving operation is longer than a time taken for the spin driving operation in the refreshing operation and a drum driving cycle including the tumbling driving operation and the spin driving operation is repeated multiple times in the refreshing operation. <EOS>
