Discussion on: 'Simple Fractional Order Model Structures and their Applications in Control System Design'

摘要

The paper by M. Tavakoli-Kakhki, M. Haeri, and M. S. Tavazoei presents a four-parameter and a five-parameter model structure to characterize the dynamic response of a system possessing an S-shaped step response. Different strategies were proposed for estimating the parameters of the approximating models. For these simple model structures new control design methods were introduced and some existing methods were modified. Finally, some numerical examples were provided to show the applicability of the proposed procedures.
