PI's Parameter Optimization Based On IWO For Optimal Controlling Of A Buck Converter's Output

Abstract

In this study, the output value of a Buck Converter, which is one of the power electronics circuit topologies and used for efficient energy conduction, is controlled. The discrete time PI algorithm is used in the control process. Kp and Ki parameters of the controller are optimized in order to ensure that the control process is fault-free with the lowest cost and the reference DC voltage level. There was used Invasive Weed (IWO) for parameter optimization. Simultaneous operations of the control process were performed via Matlab-Simulink. The Success of control process were discussed by observing results.
