FUZZY LOGIC CONTROL BASED PID CONTROLLER FOR STEP DOWN DC - DC POWER CONVERTER

Power converters are vital part of many devices. Intelligent control for such a vital part is a high priority task. The paper describes about the implementation of standalone fuzzy logic controller and self - tuning fuzzy logic based PID controller in order to control a step down power converter. The software has been developed t o simulate the real time situation based on the fuzzy logic technology. Simulation results of the fuzzy logic controller are shown for t wo intelligent control methods, a fuzzy logic control and self - tuning fuzzy PID reveal better performances than the PID conventional controller .
