In this paper, optimal computation of PID (Proportional-Integral-Derivative) parameters is carried
out for a DC-DC Buck Converter by using GWO (Grey Wolf Optimizer) Algorithm. Moreover, the
results obtained using GWO are compared with HHOA (Harris Hawks Optimization Algorithm), WOA (Whale Optimization Algorithm) and GA (Genetic Algorithm). In addition, the study selects the ITSE
(Integral of Time multiplied Squared Error) as the performance measure for PID controllers, which is
widely used in literature. The comparison of the results indicates that the GWO algorithm outperforms
HHOA, WOA, and GA in terms of transient responses such as settling time, rise time, and overshoot,
leading to superior PID parameters.
