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.
