The toolkit is a set of Simulinks' blocks for simulation of constant and variable fractional order derivatives according to the Grunwald-Letnikov definition. For implementation of variable order derivatives, four types of G-L definition extensions were used. Blocks are implemented as C-MEX S-functions.

ye yang

sir,plz....tell me how to create fractional order pid (FOPID) mask block plzzz

yixing chen

i am very sorry to ask,how to use?
Error using mex (line 206)
Unable to complete successfully.

help me,3Q!


Thanks for your sharing!

thank you..

Are the 3rd and 4th definitions available?
If so please update this post
Thanks in advance


Thank you !! Very helpfull !


Very accurate and useful toolkit.
quite applicable with a very illustrative example.


Two blocks for simulation recursive Fractional Variable Order Derivatives (D-type and E-type) were added. Additionally, two examples were added and User Guide was improved.

Problem with time sampling in 2nd definition block fixed.
