PI Parameter Optimization By Fairly Algorithm For Optimal Controlling Of A Buck Converter's Output State Variable

In this paper, Buck converter circuit that is a power electronics circuit topology is handled. The dynamicbehavior of the DC voltage level which is the output magnitude of the circuit has been optimallycontrolled. The discrete time PI algorithm is chosen as the controller. In order to keep the control processcost low level, Kp and Ki which are controller parameters were optimized. Firefly algorithm (FA), whichis an iterative algorithm for optimization, has been run for the purpose. Concurrent studies of the controlprocess have been realized on Matlab-Simulink platform and the results were argued
