Abstract

In this work, the fractional-order PI (FOPI) controller has been proposed for a single-ended primary inductance converter (SEPIC). The state-space model of the converter has been developed using the state equations of the SEPIC under different operating modes. The traditional PI controller has been designed using Ziegler–Nichols method, and the performance analysis is compared with the designed FOPI controller. Both PI and FOPI controller parameters are optimized by the genetic algorithm (GA). Simulation results of FOPI-controlled SEPIC show the better result and improved performance.
