Tuning of pid controller for buck converteusing modified bacterial foraging algorithm

DC-DC converter is used to stabilize or control the DC output voltage. Many optimization techniques have been developed to turn the PID parameters. In this paper, deals with the Modified Bacterial Foraging based Optimization technique for DC–DC Buck converter. MBF algorithm is proposed new method for PID controller optimization to improve the dynamic performance of the voltage regulator. The result of simulation shows MBF- PID controller provide better performance of the Buck converter than the conventional PID controller.
