A new design approach Is presented in this study for tuning of proportional-integral-derivative (pid) controllerparameters in a DC-DC buck converter utilizing a hybrid whale optimization algorithm (WOA) with simulated annealing (SA), namely the WOASAT algorithm, which uses a tournament selection mechanism. The proposed algorithm's efficacy ensures that the optimum pidcontrollerparameters are tuned quickly and that the quality of tuning is high. A time domain performance index is utilized to validate the proposed WOASAT based pidcontroller's performance. In addition, from the comparative results of statistical analysis, frequency response analysis, transient response analysis, disturbance rejection analysis, and performance indices analysis, the proposed WOASAT-pidcontroller was found to be more efficient than the SApidcontroller and WOA-pidcontroller in enhancing the buck converter's transient response.
