Abstract
A system and method for adjusting the operating cycle of a cleaning appliance. In the present invention, a controller having a decision system receives turbidity and temperature measurements from a turbidity sensor and a temperature sensor and uses these measurements to adjust the operating cycle of the machine to the level of soil of the articles to be washed, the rate of soil removal, and the temperature of the water used for washing. In its preferred form the decision system is a fuzzy system that includes a fuzzy rule base fired as input values from the liquid temperature and liquid turbidity sensors are received. The decision system matches the rules in the fuzzy rule base to the input values and outputs a confidence value, which is used by the decision system to adjust the operating cycle.
