SWARM INTELLIGENCE ALGORITHMS IN PID CONTROLLER TUNING FOR DC DC CONVERTERS

This article presents the development and comparative analysis of proportional integral-derivative (PID) controllers tuned by swarm intelligence algorithms for DC-DC SEPIC converters. Traditional linear PID controllers, which are are utilized widely to control DC-DC converters, exhibit poor performance in control of non-linear DC-DC SEPIC converters under dynamic circumstances. To address the problem, swarm intelligence algorithms are employed to tune PID controllers. Simulations are carried out to assess key performance indicators. Results demonstrate that PID controllers tuned by swarm intelligence algorithms achieved better transient response in comparison with traditional PID controllers.
