ABSTRACT:
An inner tub of a washing machine is rapidly braked during a portion of a deceleration phase following an extraction phase of an overall spin cycle. A controller establishes the braking operation over a critical speed band or resonant frequency zone during which excessive vibrations would be developed. The critical speed band is preferably determined based on one or more signals received from speed, load, and/or out-of-balance sensors.
