Laundry treating appliance and method for controlling the same

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.

A laundry treating appliance comprising:

• a drum that receives laundry and is capable of rotating;
• a motor rotating the drum;
• a current detector detecting a current of the motor;
• and
• a controller being configured to accelerate rotation of the drum, and determine a motion speed of the drum in a drum drive motion based on a current value detected by the current detector in a decision section during the accelerated rotation of the drum, wherein the drum drive motion is set corresponding to the decision section,
• wherein the controller is configured to obtain the motion speed by an output of an output layer of a pre-trained machine-learning network based on an input to an input layer of the machine-learning network that comprises the current of the motor detected by the current detector in the decision section.
