New Challenges in Fractional Systems

Call for Papers

Fractional order differentiation consists in the generalization of classical integer differentiation to real or complex orders. From a mathematical point of view, several interpretations of fractional differentiation were proposed, but there is still a deep debate about it. The fractional differentiation and fractional integration are nonlocal operations based on an integral with a singular kernel. This explains why these operators are still not well defined and that several definitions still coexist. Since the first recorded reference work in 1695 up to the present day, many papers have been published on this subject, but much progress still to be done particularly on the relationship of these different definitions with the physical reality of a system.

A fractional order system is a system described by an integrodifferential equation involving fractional order derivatives of its input(s) and/or output(s). From a physical point of view, linear fractional derivatives and integrals order systems are not classical linear systems and not quite conventional distributed parameter systems. They are in fact halfway between these two classes of systems and are a modelling tool well suited to a wide class of phenomena with nonstandard dynamic behaviour, and the applications of fractional order systems are now well accepted in the following disciplines:

  • Signal processing (filtering, restoration, reconstruction, analysis of fractal noises, etc.)
  • Image processing (fractal environment modelling, pattern recognition, edge detection, etc.)
  • Economy (analysis of stock exchange signals, etc.)
  • Electrical engineering (modelling of motors, transformers, skin effect, etc.)
  • Electronics, telecommunications (phase locking loops, etc.)
  • Electromagnetism (modelling of complex dielectric materials, etc.)
  • Electrochemistry (modelling of batteries and ultracapacitors, etc.)
  • Thermal engineering (modelling and identification of thermal systems, etc.)
  • Mechanics, mechatronics (viscoelasticity, vibration insulation, etc.)
  • Automatic control (system identification, observation, and control of fractional systems, etc.)
  • Biology, biophysics (signal and models of biological systems, viscoelasticity in biology, etc.)
  • Physics (analysis and modelling of diffusion phenomenon, etc.)

The goal of the present special issue is to address the latest developments in the area of fractional calculus application in signals and systems. Papers describing original research work that reflects the recent theoretical advances and experimental results as well as open new avenues for research are invited on all aspects of object tracking.
