Automation on Washing Machine Using Fuzzy Logic Controller Provided with Three Input and Two Output for Setting the Temperature of Water

摘要

Washing machines are household devices that are used to wash clothes and at present it is preferred by all people. Traditional controllers have been proved to be less capable of controlling these devices and therefore, a need has arisen to apply the Fuzzy logic for such controller applications. Fuzzy logic is computer-based approach on “degrees of truthiness” rather than the usual Boolean logic on which computing is based on. It enables system designers to approach the imprecise and unambiguous problems. In this project we have proposed a washing machine controller taking in three inputs to give exact wash time and water temperature for the corresponding inputs. The objective is to minimize the time taken, the electricity consumption and water usage for washing clothes. The principle of this process is to subject input to Fuzzy arithmetic which in turn returns the value of the temperature of water and washing time.
