Washing machine and control method of the same

A control method of a washing machine comprising a cabinet, the control method comprising:

• detecting a vibration of an outer tub elastically supported on the inside of the cabinet, by a vibration sensor provided in the outer tub;
• detecting a rotation of a motor configured to rotate an inner tub provided inside of the outer tub, by a rotation sensor provided in the motor;
• and
• controlling a rotation speed of the motor based on the vibration of the outer tub and the rotation of the motor.

A washing machine, comprising:

• a water tub;
• a rotary tub, within the water tub, to accommodate laundry;
• a drive motor configured to rotate the rotary tub and perform a dehydrating process of laundry upon rotation of the rotary tub;
• a vibration sensor configured to detect an acceleration in a horizontal direction caused by a vibration of the water tub;
• a motor sensor configured to detect a rotation signal of the drive motor;
• and
• at least one processor configured to:
• control a rotation operation of the drive motor, and
• at a start of the dehydrating process, control the drive motor to perform two acceleration operations in which the rotation of the rotary tub is accelerated at a low rotation range below a predetermined number of revolutions,
• wherein the vibration sensor and the motor sensor are configured to detect the acceleration and the rotation signal, respectively, at each of the two acceleration operations.
