Fractional-Order PID Controller Design on Buck Converter with Antlion
Optimizer Algorithm
Abstract
A Fractional-order Proportional-Integrated-Derivative (FO-PID)
controller is designed for the Buck converter, which in the control
parameters are optimized by Antlion Optimization (ALO) algorithm. The
Fractional-Order concept is a beneficial scheme that can provide several
advantages such as lower sensitivity to parametric variation and noise.
Also, the ALO algorithm is a modern nature-inspired algorithm used to
tune the PID gains with better results under-constrained problems with
diverse search spaces. Considering numerous disturbance on power
converters, a FO-PID controller can be an appropriate alternative since
it has a good robustness against harmful disturbances and has simple
structure to be implemented in industrial applications. To better
examine the superiority of the proposed method, conventional FO-PID and
PID control techniques are also designed to be compared with this work.
Both simulation and experimental results verify the robustness of the
proposed method in different challenging scenarios.
