Optimal Tuning of PI^λD^μ Controller for PMDC Motor Speed Control Using Ant Colony optimization Algorithm for Enhancing Robustness of WFSs

New Optimal Control of Permanent Magnet DC Motor for Photovoltaic Wire Feeder Systems

“…Fractional-order Fuzzy logic PID (FO-Fuzzy-PI) structure utilized in this research paper has fractional-order Fuzzy PI and Fractional-order Fuzzy PD controllers [6]. On this basis, we realized a FO-Fuzzy-PID controller for solar PVWFS system and its structure is illustrated in Figure 9.…”

“…The FO-Fuzzy-PID controllers have higher performance when compared to traditional PID regulators [6]. The critical coefficient concerning the FO-Fuzzy-PID regulator is, its performance extremely depends on its scaling factors (i.e.…”

“…PSO algorithm is a swarm intelligence bio-inspired population-based search process that was introduced by Kennedy for finding approximate solutions in search and optimisation problems [21]. Some utilizations of PSO algorithm are in the domain of nonlinear systems, computer science, robotics, engineering and many others in the realworld applications [6,22]. Because the PSO algorithm is an outstanding optimization method and a promising approach for solving the optimal controller parameters problem [23].…”

“…The possible solutions p1, …, pn are named particles. The PSO method explores the entire space of possible solutions, where the particles 'move' to search for the global best-fit solution 'Gbest' [6]. Each individual has a velocity Vi k and position Xi k associated to it.…”

“…Such limitations may lead to welding under non-optimal conditions due to wire feed speeds that are outside the optimal range for the given welding operation, owing to the natural tolerances of wire drive motors and related mechanisms. Numerous solutions have been proposed in the literature to improve the wire-feed speed responses of WFSs, either by developing new systems with different types of PMDC motors or by designing robust wire-feeder controllers [4][5][6][7][8].…”
