“…In terms of efficient tuning, the metaheuristic algorithms have also demonstrated greater capabilities for AVR system control, as well. Some of the metaheuristic optimization algorithms that were used to improve the performance of the abovementioned controllers are improved spotted hyena optimization (Zhou et al, 2020), water cycle algorithm (Pachauri, 2020), ant lion optimization (Pradhan et al, 2018), teaching–learning based optimization (Chatterjee and Mukherjee, 2016), artificial ecosystem-based optimization (Ćalasan et al, 2020), bacterial foraging optimization (Anbarasi and Muralidharan, 2016), African buffalo optimization (Odili et al, 2017), firefly algorithm (Bendjeghaba, 2014), particle swarm optimization (Ghosh et al, 2021; Li et al, 2017), improved jaya algorithm (Bhookya and Jatoth, 2020), multi-objective extremal optimization (Zeng et al, 2015), and swarm learning process (Pongfai et al, 2020). The list can further be extended.…”
