摘要：In the last years, control theory has appliedfractional calculus, and the results are unquestionable. Theclassic PI controllers have been modified with fractionalcalculus creating the Fractional Order Proportional-Integral(FOPI). The FOPI controllers have performed better thanconventional PI because they provide more flexibility in thecontroller design. The use of PI controllers remains of highimpact on modern power systems, and for this reason, it isimportant to continue analyzing their implementation withsome variants. One of the elements that continue to bemost studied in modern power systems is the converter and,recently, the synchronous Buck converter that increases theefficiency reducing the conduction losses. In this work, a novelreal-time fractional order control approach is applied overa Synchronous Buck converter. The results are validated insimulation and under a Real-Time simulator. In order toevaluate the performance of the proposed FOPI controller, twoscenarios are considered: variable reference and variable load,where the proposed FOPI controller outperforms the classicalPI controller.
