Reduced order approximation of incommensurate fractional order systems
2019 IEEE Conference on Control Technology and Applications (CCTA), 2019Model order approximation of an incommensurate fractional order system is a highly challenging problem by any analytical technique. In view of this, a simple and a computationally efficient approach is proposed for the model order reduction of incommensurate fractional order systems. The proposed approach is based on FOMCON toolbox of MATLAB and hybrid

Reduced Order Approximation of MIMO Fractional Order Systems
IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2013A new two-stage method for reduced integer order approximation of fractional multiple-input, multiple-output (MIMO) systems is proposed. In the first stage, the transfer function matrix (TFM) Gf(s) of the given fractional order MIMO system is obtained and an integer order approximate TFM R(s) is formed by applying an existing approximation method to ...

Spectral Approximation of Third-Order Problems
Journal of Scientific Computing, 1999The author introduces a Chebyshev collocation method for the partial differential equation \(u_t = u_{xxx}\) on the set \((x, t) \in (-1, 1) \times (0, T]\). The boundary conditions are of a Dirichlet sort which ensure stability. A computational investigation suggests that collocation at the Gauss-Lobatto points produces a stable numerical method.

Approximation of Fractional-Order Operators
2019In order to deal with some difficult problems in fractional-order systems, like computing analytical time responses such as unit impulse and step responses; some rational approximations for the fractional-order operators are presented with satisfying results in simulation and realization.

A note on the “order of approximation”
International Journal of Solids and Structures, 1985In this very short note, a procedure is given for finding the nodal order of error for some finite element models, and one proves the superconvergence of one-dimensional problems of Pin Tong kind.

The use of fractional-order (FO) calculus for the solution of different problems in many fields has increased recently. However, the usage of FO system models in practice brings some difficulties. The FO operator, fractance device, is usually realized via several integer-order approximation methods, which have pros and cons in the aspect of operation ...
