Figure 8. Output Voltage under Variation of FOSEPIC Orders
Figure 8 displays the output voltage variations corresponding to
different combinations of FOSEPIC orders. Panel (a) illustrates the
response for the combination of orders [Yellow] (0.6, 0.28, 0.4,
0.9), while panel (b) shows [Magenta] (0.9, 0.5, 0.4, 0.9). Panel
(c) presents the output for [Green] (0.17, 0.25, 0.35, 0.69), and
panel (d) displays the results for [Red] (0.75, 0.5, 0.2, 0.85).
These results highlight how different order combinations affect the
output voltage stability and regulation.
Comparison of FOSMC and SMC for FOSEPIC Converter
In the comparison of the fractional-order sliding mode controller
(FOSMC) and the traditional sliding mode controller (SMC) for the
FOSEPIC converter, as shown in figure 9 for boost mode, the FOSMC
effectively minimizes oscillations that are prevalent in the SMC for the
SEPIC configuration. This enhanced stability is similarly observed in
the buck mode operation, indicating the superior performance of the
FOSMC in maintaining output voltage regulation across varying operating
conditions.
