A Fast Firefly Algorithm for Function Optimization: Application to the Control of BLDC Motor

Abstract

Firefly Algorithm (FA) is a recent swarm intelligence first introduced by X.S. Yang in 2008. It has been widely used to solve several optimization problems. Since then, many research works were elaborated presenting modified versions intending to improve performances of the standard one. Consequently, this article aims to present an accelerated variant compared to the original Algorithm. Through the resolving of some benchmark functions to reach optimal solution, obtained results demonstrate the superiority of the suggested alternative, so-called Fast Firefly Algorithm (FFA), when faced with those of the standard FA in term of convergence fastness to the global solution according to an almost similar precision. Additionally, a successful application for the control of a brushless direct current electric motor (BLDC) motor by optimization of the Proportional Integral (PI) regulator parameters is given. These parameters are optimized by the FFA, FA, GA, PSO and ABC algorithms using the IAE, ISE, ITAE and ISTE performance criteria.

Reducing the Electronic Nose Sensor Array for Asthma Detection Using Firefly Algorithm

“…Based on the manners of fireflies, this algorithm utilizes the concepts of attraction, brightness, and movement to efficiently examine and explore optimal solutions in the problem space [18]. There are three principles to explain these fireflies [38]:…”

Control of the BLDC Motor Using Ant Colony Optimization Algorithm for Tuning PID Parameters

“…Milani et al (2012) determined ideal reduced rise time, settling time, and overshoot on system response using the proposed PID parameters BLDC motor PID -PSO -Ziegler-Nichols algorithm. Bazi et al (2021) presented a fast firefly algorithm (FA) algorithm and contrasted it with a standard FA through the use of various standard benchmark functions. The comparison of the simulation results was then performed while also taking the speed and accuracy of the criteria for comparing the algorithms into account.…”

Full-duplex QoS Optimization using Enhanced firefly Algorithm

“…αS and αM (0,1) are bitwise preference indications, with 1 indicating that the relevant RRH executes DL broadcast and 0 indicating UL receptions for the RRH. pS(k-i) and pM(k-i) are the energy allocations from the k th SA-RRH and k th MA-RRH to the i th DL UE, correspondingly [16]. gD(k-i) is the signal amplitude as from k th SA-RRH towards the i th DL UE and network velocity as from k th MA-RRH towards the i th DL UE.…”
