Fractional-order ADRC framework for fractional-order parallel systems

2020 39th Chinese Control Conference (CCC), 2020
This study discusses the control of parallel fractional order systems (FOSs) by the fractional-order active disturbance rejection control (FOADRC) technique. The FOADRC framework for linear FOSs and the necessary conditions for the existence of a stable controller of the system are given.

Computation of Orders of a Commensurable Fractional Order Model

2019 IEEE 58th Conference on Decision and Control (CDC), 2019
This paper deals with the calculation of the system order and the determination of the input order of a commensurable fractional order model. The system and input orders are equal to the number of system and input parameters, respectively. The benefit of the proposed method is that no search algorithms or over-parameterized equations have to be used ...

Variable Order and Distributed Order Fractional Operators

Nonlinear Dynamics, 2002
Many physical processes appear to exhibit fractional order behaviour that may vary with time or space. The continuum of order in the fractional calculus allows the order of the fractional operator to be considered as a variable. The paper develops the concept of variable and distributed order fractional operators.

Fractional-Order Models of the Ultracapacitors

2013
In the paper, dynamic behavior of the ultracapacitors is investigated and analyzed. The ultracapacitors are represented by equivalent electrical circuit models and mathematically described by fractional-order differential equations. The identification procedure is proposed to identify the parameters of the models.

Fractional-order observers design for fractional-order systems with unknown inputs

2012
This paper considers a method to design the functional observers for continuous-time linear fractional-order systems with unknown inputs. The conditions for the existence of these observers are given. Sufficient conditions for the asymptotical stability of observers with the fractional-order satisfying ...
