Abstract

In this paper, a DC-DC converter with variable and constant input voltage conditions is controlled by a PID (Proportional-Integral-Derivative) controller. In order to overcome the non-linear conditions that occur in industrial systems, a SEPIC converter that can increase, decrease and hold the voltage constant without changing the poles is selected. The parameters of the PID controller are tuned with the Artificial Rabbit Algorithm and Cohen-Coon classical method to provide a linear response to the specified variable conditions. The methods were compared in terms of rise time (Tr), overshoot (Mp) and peak value (Vmax). Simulation results in MATLAB/Simulink show that the controller performance obtained with the metaheuristic algorithm is the same as that of the Cohen-Coon manual method. The study highlights the importance of the combination of power electronics, metaheuristics and classical methods in industrial systems.
