The parameters of each controller were tuned with four evolutionary optimization algorithms (Social Spider Optimization (SSO), Swarm Optimization (PSO), Genetic Algorithm (GA), and Particle Ant Colony Optimization (ACO)). The comparisons were carried out between the two controllers IOFPID and FOFPID, as well as among the four optimization algorithms for the two controllers. The results of comparisons proved that the FOFPID controller with SSO has achieved the best time response char- acteristics and the least tuning time.hufuzzy PIDfractional order PIDGAACOPSOSSOhttps://akjournals.com/view/journals/1848/14/1/article-p1.xml10.1556/1848.2021.00375International Review of Applied Sciences and Engineering114
