Improving the Efficiencies of Elevator Systems Using Fuzzy Logic

Abstract

This research presents the application of fuzzy logic in elevators. This analyzes the features of elevators and how fuzzy logiccould be used to minimize the waiting time, detect when the temperature is high for the car, and determine which floor hashighest number of people waiting for the car. High rising building is a common sight in most of the cities today. Fast andefficient elevator transportation is a key feature when creating these kinds of buildings. As the complexity of a systemincreases, it becomes more difficult and eventually impossible to make a precise statement about its behaviour. Many of thesystems build before fuzzy logic use trial and error and effort had to be done over and over to arrive at effective control.Fuzzy logic concepts are used to enable the elevator control system to make decisions. The design criteria include ofoptimizing movement of elevators with regard to several factors such as waiting time, riding time, energy, load, etc.Software simulation is done in order to capture the performance of the proposed system which is compared to conventionalapproaches.Keywords: Fuzzy logic (FL), Elevator.
