Abstract
In this work, a new nature-inspired, population-based meta-heuristic optimization method, Harris Hawks Optimization (HHO), is applied for the first time for tuning the parameters of both the traditional PID controller and the fractional order PID (FOPID) controller used in a DC-DC buck converter. The PID and FOPID controllers, whose parameters optimally tuned by HHO algorithm, are used for improving the transient response of a DC-DC buck converter by minimizing the maximum overshoot, settling time and rise time of converter's output voltage and for eliminating the steady state error. In addition, to illustrate the superiority of the proposed HHO-PID and HHO-FOPID controllers, beside the transient response analysis, the frequency response analysis and performance indices analysis were also conducted and compared with GA-PID and WOA-PID controllers, which are available in literature and are tuned by genetic algorithm (GA) and whale optimization algorithm (WOA), respectively. The numerical and graphical results demonstrated that the proposed HHO-FOPID controller has better control performance than the proposed HHO-PID, GA-PID, and WOA-PID controllers. The obtained simulation results confirmed the superiority and effectiveness of the proposed HHO-FOPID controller in terms of both algorithm and controller structure.
