| Summary: | The elevator technologies are developed to serve the
requested passenger’s floors with high consideration of
passengers’ satisfaction and elevator optimal performance.
Responding to the issue, this paper focuses on development
of an elevator group controller based on fuzzy algorithm. By
introducing a fuzzy controller in an elevator system, this
system is developed to manage the required passenger traffic
density keeping passenger waiting times within reasonable
limits. To increase the performance of the elevator group three
major linguistic variables are introduced within a set of fuzzy
rules. These include the average waiting time (AWT), power
consumption (PC), and floor traffic (FT). When the passenger
traffic is high, the low fuzzy control values reduce the importance
of priority of floors rather the estimated arrival time is to be
minimized. The simulation was accomplished to check the
priority of fuzzy system graphically while the actual
prototype of elevator system is programmed by PIC device
as a controller. As a result a set of fuzzy rules was drawn
based on practical considerations; mainly minimization of
waiting time and energy consumption. When a few hall requests
are registered, the elevator controller will decide which one of the
elevators will serve which of the incoming hall requests. In order
to manifest the work with actual elevator service, a computer
simulation of a four-cars-elevator controller in a twenty
storied building is accomplished by using MATLAB™ fuzzy
logic toolbox and implements the prototype experimental model
of a 3 car 4 storied |
