This paper proposes the newest modified version of the flower pollination algorithm (FPA) named the parallel flower pollination algorithm (PFPA) and its application to design the optimal fractional-order proportional-integral-derivative (FOPID) controller for the fractional-order brushless direct current (BLDC) motor speed control system. The proposed PFPA is based on the time sharing strategy employing the multiple point single strategy (MPSS) method which is efficiently run on a single CPU platform. The search performance of the PFPA over the original FPA investigated against 10 benchmark functions is presented in this paper. For the fractional-control application based on the modern optimization, results of the FOPID controller designed by the PFPA for the BLDC motor speed control system are compared with those of the integer-order PID (IOPID) controller designed by the PFPA. As results, it was found that the BLDC motor speed controlled system with the FOPID controller designed by the proposed PFPA can provide very satisfactory responses superior to that with the IOPID controller designed by the FPA, significantly.

W artykule opisano nową zmodyfikowana wersję algorytmu zapytania FPA i jego zastosowanie do projektu sterownika do bezszczotkowego silnika BLDC. Zaprezentowano benchmark dziesięciu funkcji i potwierdzono lepsze parametry w porównaniu z konwencjonalnym sterownikiem IOPID.
