Particle Swarm Optimization for improved performance of PID controller on Buck converter

Nowadays DC-DC Converters are used for controlling and stabilizing DC voltages, feeding electric vehicles, telephone sets and industrial inverters. Recently improving the performance of the DC-DC converters is one of the goals of engineers in the industries and several control methods are used to control Buck converters. In this paper, PI and PID controllers are used to optimize the DC-DC converter performance. In order to obtain the best coefficients of the controllers, particle swarm optimization (PSO) method is applied. The results of simulation show the capability of the PSO method in designing an optimized PID controller which improves the performance of the above-mentioned converter.
