Abstract
Nowadays, in Libyan households, washing machines are very common items. It is not only a big time saver over hand washing, but also it saves a great effort, people can carry out another task and then return back to the machine to get their clothes clean and even dry. The only things they need to do are load the clothes into the machine, throw detergent in, run it, and walk away. This paper shows the importance of fuzzy logic control based washing machine to get a suitable wash, rinse, and spin time for different types and amount of clothes and amount of dirtiness. The process is based on fuzzy inference system. The signals that come out from sensors are fed to the fuzzy controller as non-precise inputs to get the desired output (a crisp value of washing time, rinsing time and spinning time). The Simulation was done by MATLAB’s fuzzy logic toolbox.
Highlights
Fuzzy logic controller has many practical advantages over the other controllers, because of its simplicity, effectively, and flexibility, and it can handle problems with imprecise and incomplete data, giving us a desired data with very accurate and precise results corresponding on a wide range of operating conditions expressed in linguistic terms
In general when we use washing machine, we load the clothes into the machine, throw detergent in, select the duration of washing time based on type and amount of clothes and type of dirtiness or greasy and run it
Once switch the washing machine on, sensors sense these parameters which are considered in this paper as inputs that will be fed to the fuzzy controller to get the exact outputs which are considered in this paper as wash time, rinse and spin time
Summary
Fuzzy logic controller has many practical advantages over the other controllers, because of its simplicity, effectively, and flexibility, and it can handle problems with imprecise and incomplete data, giving us a desired data with very accurate and precise results corresponding on a wide range of operating conditions expressed in linguistic terms. In 2015, Hatagar and Halase objected to save lot of time, electricity and water for washing the cloth They considered type-of-dirt and dirtiness of clothes as inputs to fuzzy controller [9]. Anita ,and Bhawna Hooda in same year, 2016, have proposed the design of fuzzy logic controller which is having five inputs to give an exact wash, rinse and spin time of fully automatic machine. The objective of this is only to save a lot of time, electricity, detergent and water for washing the cloth. Fuzzy logic control system can be used to calculate the processing time of washing machine for different cloths
