A washing machine is provided that includes a washing tub, a driver to rotate the washing tub, a sensor to sense an operation of the washing machine, and at least one processor configured to obtain a weight of dry fabric of laundry in the washing tub, control the driver to rotate the washing tub at a speed within a first range, and obtain a first torque axis current of the driver. The at least one processor is further configured to, after supplying washing water to the washing tub, control the driver to rotate the washing tub at a speed within a second range and obtain a second torque axis current of the driver, and identify a material of the laundry by inputting at least one of the weight of the dry fabric, the first torque axis current, or the second torque axis current to a neural network model.

Washing machine and control method thereof

A washer includes a drum, a motor connected to the drum, a motor drive connected to the motor and configured to supply a driving current to the motor to rotate the drum, and a processor connected to the motor drive. The processor is configured to control the motor drive to supply the driving current to the motor to rotate the motor at a target speed and to determine a magnitude of a load accommodated in the drum while controlling a rotational speed of the motor within a predetermined range.
