“…The fine tuning of fractional order PID control is challenging compared to conventional PID control due to the existence of extra two parameters and to meet some special constraints like gain margin, phase margin, gain crossover frequency, and sensitivity conditions. Nevertheless, evident from a literature shows that the development of the meta-heuristic methods are created the tuning of constraints very ease [21][22][23] in last few years such as genetic algorithm [24,25], Big bang big crunch algorithm [26], particle swarm optimization [27], bacterial foraging optimization algorithm [22,23,28], artificial bee colony algorithm [29,30], stochastic multi-parameters divergence optimization [31], multi objective optimization design [32], cuckoo search algorithm [33,34], bacterial foraging chemotaxis gravitational search algorithm [35], differential evolution [36], chaotic ant swarm optimization [37], gases brownian motion optimization [38], bat algorithm [39], tabu search algorithm [40] than analytical approach.…”
