1. A method for controlling a laundry treating apparatus that includes a tub configured to receive water and a drum rotatably disposed in the tub and configured to receive laundry, the method comprising:
rotating the drum to move the laundry in the drum relative to water in the tub;
draining water in the tub to an outside of the tub;
controlling a rotation speed of the drum to a first speed that is preset;
maintaining the first speed of the drum based on the rotation speed of the drum reaching the first speed;
determining a first measured value related to a magnitude of unbalance of the laundry while rotating the drum at the first speed;
based on the first measured value being less than or equal to a first reference value, accelerating the drum to a second speed that is preset;
maintaining the second speed of the drum based on the rotation speed of the drum reaching the second speed;
determining a second measured value related to the magnitude of unbalance of the laundry while rotating the drum at the second speed;
stopping rotation of the drum based on the second measured value being less than or equal to a second reference value;
accelerating the drum to a third speed greater than the second speed to thereby remove water from the laundry;
determining a third measured value related to the magnitude of unbalance of the laundry while accelerating the drum to the third speed; and
stopping rotation of the drum based on the third measured value becoming greater than an unbalance reference value while rotating the drum at the third speed, the unbalance reference value being set based on the second measured value.
