N2 - The negative impedance characteristic of the constant power loads (CPLs) causes instability in dc/dc converters in the dc microgrids (MGs). To improve the stability of the dc/dc converter feeding CPLs, a robust and fast controller is required. This brief presents a robust pulse-width modulation-based type-II fuzzy controller for a dc/dc boost converter feeding the CPL in a dc MG. Theoretical analysis and real-time simulation are presented to demonstrate the effectiveness of the proposed non-integer intelligent controller. Finally, the experimental results demonstrate that the proposed intelligent controller for the dc/dc converter has a faster and more robust response in comparison to the previously suggested control techniques.
