Dear Das,

Maybe the following links may help you:

1 - Modeling and Simulation of Fractional Order Chaotic Systems Using Matlab/Simulink

(http://www.vsrdjournals.com/EEC/Issue/2011_6_June/5_Prem_Bhushan_Mital_Review_Article_June_2011.pdf)

2 - Fractional Derivatives, Fractional Integrals, and Fractional Differential Equations in Matlab

(http://cdn.intechopen.com/pdfs/21383/InTech-Fractional_derivatives_fractional_integrals_and_fractional_differential_equations_in_matlab.pdf)

3 - MATLAB TOOLBOXES FOR FRACTIONAL ORDER CONTROL: AN OVERVIEW

(http://www.daaam.info/Downloads/Pdfs/proceedings/proceedings_2011/p21144d1_Matusu.pdf)

Jaderson, the link is corrupted. May you give us the correct link? Thanks.

Hello Paulo Cezar,

Number 1 is internet based Journal. However, It is down now:

http://dl.acm.org/citation.cfm?id=1702545

Number 2 still working.

Number 3 is no longer available for free:

(http://connection.ebscohost.com/c/articles/69985066/matlab-toolboxes-fractional-order-control-overview).

Pehaps, someone has downloaded them and migth send you a copy.

Thanks, the last one maybe I will download from CAPES's website.

You may check YQ Chen's tutorial paper (http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5160719&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F5089257%2F5159764%2F05160719.pdf%3Farnumber%3D5160719)

you may use FOTF toolbox or FOMCOM toolbox .
