| Abstract | In this paper, a fuzzy logic auto-tuning scheme is proposed to improve the dynamic performance of DC-DC converters by achieving a robust output voltage against load disturbances. The presented two-level control approach adopts the advantages of both fuzzy logic and classical PID controllers in handling with the system's non-linear characteristics. The method is general and simple enough to be applied to any DC-DC converter topology. This paper also presents a large-signal simulation model, which illustrates the effect of the nonlinear nature of switching mode DC-DC converters. |
