Published in 2018 at "IFAC-PapersOnLine"

DOI: 10.1016/j.ifacol.2018.06.021

Abstract: Abstract This paper proposes fractional order autotuner controller for the benchmark refrigeration system. The method is an extension of a previously presented autotuning principle and produces a robust fractional order PI controller to gain variations.… read more here.

Published in 2018 at "IFAC-PapersOnLine"

DOI: 10.1016/j.ifacol.2018.06.023

Abstract: Abstract This paper studies the performance of discrete-time fractional order controllers. The fractional derivatives and integrals are numerically implemented by means of a generalized mean of discrete generating functions. The two additional degrees of freedom… read more here.

Published in 2020 at "ISA transactions"

DOI: 10.1016/j.isatra.2020.05.022

Abstract: This paper presents a new optimization-based tuning method for fractional- and integer-order controllers. The method is based on minimizing an arbitrary cost function which is taken here as the integrated absolute tracking error, and it… read more here.

Published in 2018 at "IEEE Latin America Transactions"

DOI: 10.1109/tla.2018.8789564

Abstract: In this paper a simulated study of the application of fractional order controllers (FOC) to back–to-back (BTB) converters is presented. A comparison with the corresponding integer order controller is dicussed. The study is performed in… read more here.
