Comparative Evaluation of PID Voltage Mode, PI Current Mode, Fuzzy and PWM Based Sliding Mode Control for DC-DC Converters

This paper presents a comparison between the application of four control techniques in DC-DC converters. PID voltage mode (PID-VM), PI current mode (PI-CM), fuzzy, and PWM based sliding mode (SM) controllers are applied to buck converter. The design procedures of controllers are reviewed. The dynamic performance of these controllers under star-up, steady state, input voltage variation, load current disturbances and EMI spectrum are presented and compared.
