Abstract
A control method of a laundry treating apparatus includes rotating a drum at a reference rotational speed that is lower or higher than a resonance rotational speed of the laundry treating apparatus; measuring the maximum displacements of tub front and rear surfaces and a phase difference between the maximum displacements during the rotation of the drum at the reference rotational speed; determining a front unbalance (UB) mass located in a drum front area, a rear UB mass located in a drum rear area, and an angle between the UB masses based on the maximum displacements and the phase difference; and accelerating a drum rotational speed to a target rotational speed that is higher than the reference rotational speed and the resonance rotational speed, when the front and rear UB masses are in a preset allowable mass range and an angle between the UB masses is in an allowable angle range.
