1. A laundry treating appliance comprising:
a drum at least partially defining a treating chamber for receiving a laundry load for treatment according to a cycle of operation;
a motor operably coupled with the drum to rotate the drum at least during a measurement period;
at least one balance ring mounted to the drum and defining an internal annular cavity in which a mass is located; and
a controller configured to determine, during the measurement period, at least one of a torque of the motor, an acceleration of the drum, a rotational speed of the drum, or an angular position of the drum the controller further having a parameter estimator to repeatedly estimate a relative position of the mass and a relative position of the laundry load based upon at least one of the torque, the acceleration, the rotational speed, or the angular position of the drum as the drum rotates and wherein the controller is further configured to accelerate the rotational speed of the drum during the cycle of operation when the relative position of the mass is determined to be angularly spaced from the relative position of the laundry load.
