Claim 10:
11. A laundry treating appliance comprising:
a drum configured to receive laundry;
a motor rotating the drum;
a detector detecting a current of the motor; and
a controller being configured to accelerate rotation of the drum, obtain a current change function based on current values detected by the detector at a predetermined time interval during the accelerated rotation of the drum, obtain an inflection point at which a value of the second derivative in the current change function changes from negative to positive, and determine a motion speed based on a rotation speed of the motor corresponding to the inflection point, wherein the current change function is a continuous function representing the current of the motor according to a rotational speed of the motor,
wherein the controller is configured to rotate the motor in the motion speed after determining the motion speed.
