Fractional order differentiation consists in the generalisation of classical integer differentiation to real or complex orders.

During the last decades, fractional differentiation has drawn increasing attention in the study of the so-called anomalous social and physical behaviors, where scaling power law of fractional order appears universal as an empirical description of such complex phenomena.

The goal of this special issue is to address the latest developments in the area of fractional calculus application in dynamical systems. Papers describing original research work that reflects the recent theoretical advances and experimental results as well as new topics for research are invited on all aspects of object tracking. Potential topics include, but are not limited to:

• Modeling and applications of complex systems in physics, biology, biophysics, and medicine
• Fractional variational principles
• Continuous time random walk
• Computational fractional derivative equations
• Viscoelasticity
• Fractional differential equations
• Fractional operators on fractals
• Local fractional derivatives
• Automatic control
• Thermal systems
• Electromagnetism
• Economical and financial systems
• Electrical, mechanical, and thermal systems
• Bifurcation
• Chaos
• Synchronization
