Ahmadi Dastjerdi, A. (author), Vinagre, Blas M. (author), Chen, Yang Quan (author), Hassan HosseinNia, S. (author)Today, there is a great tendency toward using fractional calculus to solve engineering problems. The control is one of the fields in which fractional calculus has attracted a lot of attention. On the one hand, fractional order dynamic models simulate characteristics of real dynamic systems better than integer order models. On the other hand,...review 2019

Valério, D.P.M.O. (author), Saikumar, N. (author), Ahmadi Dastjerdi, A. (author), Karbasizadeh, Nima (author), Hassan HosseinNia, S. (author)A controller with the frequency response of a complex order derivative may have a gain that decreases with frequency, while the phase increases. This behaviour may be desirable to ensure simultaneous rejection of high-frequency noise and robustness to variations of the open-loop gain. Implementations of such complex order controllers found in...journal article 2019
