Optimization of electrical energy in the fan using fuzzy logic controllers

Abstract Single-phase induction motors are a type of electric machine that are widely used in people’s lives due to it has advantages such as lower prices, simple maintenance and construction. However, the single-phase induction motor also has a weakness, which is difficulty in setting up the rotation. The rotation setting of a single-phase induction motor can be affected by changes in the input frequency and changes in the input voltage. In this study is to design the control of a single-phase induction motor in a commonly used fan. The speed of the single-phase induction motor is regulated based on the number of visitors, using artificial intelligence namely fuzzy logic. The fuzzy logic controller can be group visitors to the room to determine the speed of the fan. The visitors are divided into three groups, namely “many” to indicate the maximum speed, “medium” for medium speed and “few” for low speed. Therefore, this research may contribute as an energy-saving solution using artificial intelligence.
