Special Issue Information
Dear Colleagues,
The state of a dynamical system consists in the information that, together with the input, uniquely determines the output. In many cases, research on control theory is carried out under the supposition that the whole state is known by means of external measurements using a sensor. However, it is well known that one can use fewer sensors than there are states of systems due to economic costs or technological limitations. One of the more famous solutions to this problem is the design of algorithms of estimation or observers, i.e., dynamical systems capable of estimating internal information from measurements of the available input and output of that system. To encompass as much as possible all the properties of the system dynamics and to obtain more accurate and flexible structures, research has been conducted employing different modeling approaches using fractional calculus. Fractional calculus is a generalization of conventional integer-order calculus employing integrodifferential operators, for example, Caputo, Riemann–Liouville, Atangana–Baleanu, or Caputo–Fabrizio. Further generalizations are possible with Prabhakar fractional operators, Sonine-like generalized operators, and conformable and distributed-order derivatives.
This Special Issue addresses the newest developments in nonlinear observers’ theory of fractional-order systems modeled with different integrodifferential operators, convergence analysis utilizing the Lyapunov approach, observability properties of certain classes of nonlinear fractional-order systems, state reconstruction design by means of asymptotic and finite-time observers, observer-based controllers, separation principles in fractional systems, synchronization, and fault estimation.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fractal and Fractional is an international peer-reviewed open access monthly journal published by MDPI.
