Engineering the FUZZY RULE SET

At the end of an additional time T2 the total quantity of absorbed water is measured. This term Suction Amount is defined as the total absorbing capacity of the introduced load. Through this, a large amount of absorbed water corresponds to a large load, a small amount of water to a small load. The results of the experiments show that the type and size of a washing load is related to the Suction Speed and the Suction Amount . Apart from this recognized tendency (Fig. 5.67), the results are somewhat fuzzy and thus justify the use of FUZZY CONTROL . 

The combination of the two values Suction Speed and Suction Amount (Fig. 5.68) allows a relatively precise value of the expected water demand in the main wash to be determined. From experiments this derived amount of wash water ( First Water Demand ) is added shortly after the end of the measurement. In cases where the laundry needs still more water the water level will eventually

The resulting value of Total Water Consumption and the result of the summed up value on-times , defined as the Amount of Absorbed Water , form the foundation for the attachment of the Rinse Water Demand . 

However, the amount of rinse water results not only from the amount of water used in the main wash, which now has to be removed, but also depends on the number of rinse cycles that are to follow on and the spinning intensity at the beginning of each rinse cycle. The sum of all these influencing factors finally leads to the required amount of rinse water that is put in at the beginning of each rinse cycle.
