Abstract:
1. A method of determining when a laundry load has satellized within a rotating drum of a laundry treating appliance having a motor for rotating the drum and a controller for controlling the rotation of the drum, the method comprising: accelerating the rotational speed of the drum from a non-satellizing speed to a satellizing speed by supplying a control signal from the controller to the motor; monitoring a high frequency component of a torque signal of the motor by applying, during the accelerating, one of a high pass filter, a band pass filter, and a band stop filter to the torque signal, to permit the passing of frequencies greater than the drum frequency to generate a filtered torque signal, with the high frequency component having a frequency greater than a rotational frequency of the drum; determining that the load is satellized when the amplitude of the high frequency component lies below a predetermined threshold relative to zero.
