Abstract
A method and apparatus of adaptively filling a washing machine uses a water level signal from an analog pressure sensor to determine the appropriate fill level of the machine. A fuzzy logic knowledge base uses various inputs which are scaled and added together to create an output value. The inputs to the fuzzy logic knowledge base include the current pre-defined level, the Ross input, the last rate difference value, and the peak rate level. The present invention may also be used to determine the fabric type of the clothing in the washing machine.
