Abstract – Fractional calculus is the branch of mathematics that generalizes the operations of classical calculus. The dynamics of real-world systems can be more effectively captured using the concepts of fractional calculus compared to classical calculus-based models. This is due to the additional degrees of freedom (extra "tuning knobs") available in a fractional-order transfer function, which, in turn, enhances the design flexibility.

In recent years, optimization (both classical and metaheuristic) techniques have been exploited by researchers to obtain robust fractional-order models. The application of numerical approximation methods has resulted in effective fractional-order systems for various engineering disciplines, such as linear and non-linear circuit theory, signal processing, biomedicine, control theory, etc.

Another critical aspect of research in fractional-order systems is their interdisciplinary subject. In particular, it is an area in which applied mathematics, biochemistry, material science, and engineering disciplines overlap, which leads to many new potential applications.

This talk aims to provide an overview of the current state of research in the design, realization, and application domain of fractional-order systems, highlighting particular issues that need to be addressed and future directions.
