Washing machine and control method thereof

Abstract

A washing machine includes a drum accommodating laundry, a motor configured to rotate the drum, a speed sensor configured to detect a rotational speed of the drum, and a processor. The processor configured to: determine a mass of the laundry corresponding to each of a first acceleration section and a second acceleration section based on the rotational speed detected by the speed sensor, and control the motor such that an absolute value of the rotational speed at a start time of the first acceleration section is substantially the same as an absolute value of a rotational speed at a start time of the second acceleration section. A rotational direction of the drum corresponding to the rotational speed at the start time of the first acceleration section is opposite to a rotational direction of the drum corresponding to the rotational speed at the start time of the second acceleration section.
