A Novel Approach for Designing FKBC Based Washing Machine Controller

Abstract

The thing is that the washing machines used are not as automatic as they should be and can be. This paper aims at presenting the idea of controlling the washing time using fuzzy Knowledge Based Control (FKBC). The paper describes the procedure that can be used to get a suitable washing time for different cloths. The process is based entirely on the principle of taking non-precise inputs from the sensors, subjecting them to fuzzy arithmetic and obtaining a crisp value of the washing time. It is quite clear from the paper itself that this method can be used in practice to further automate the washing machines. Never the less, this method, though with much larger number of input parameters and further complex situations, is being used by the giants like LG and Samsung.
