The FOMCON toolbox for MATLAB is a fractional-order calculus based toolbox for system modeling and control design.
Dear Prof Aleksei
I am very grateful for your interest. Thank you for opening FOMCON website.
I need tutorial about codes so i try to reach FOMCON website. Analysis, control and modelling of fractional order systems if your crew can share with us it will very helpfull for us.
@taner: thanks for pointing that out. Although the FOMCON website is no longer actively maintained, the information provided there can still be useful.
I cant reach the site which is written next line. Can you please reactive that site.
Thank you so much!
I need help for the fractional derivative of matrix how can do this.
I'm a research scholar in Anna University.
I can't able and I don't know the actual procedure for uploading FOMCON toolbox in my Matlab 2014a software. Kindly support for updating the toolbox.
KIndly support for this issue. I'm waiting for your positive support for this.
Thank you the tool box is very helpful, i want to know if there are document explains the tools?, Thank you
Tarun Varshney, you should add ALL toolbox files/folders to MATLAB path. It seems that in your case MATLAB is not aware of the isstable() function implemented specifically for FOTF objects.
When I am trying to analyze the fractional order systems using fotf_gui.m, as I insert the system 'G' as shown in example number 1, facing a problem in stability test. I am getting an error
Stability test for 'G'
Error using isstable
Too many output arguments.
Error in fotf_gui>btnStable_Callback (line 89)
[K,q,err,apol] = isstable(myFotf, true)
Error in gui_mainfcn (line 95)
Error in fotf_gui (line 25)
Error while evaluating UIControl Callback.
Kindly help me out.
when I try to identify one model ,it shows 'lsqnonlin stopped because it exceeded the function evaluation limit,
options.MaxFunctionEvaluations = 1200 (the default value). 'and than goes wrong,where to chang this default value, and when I stop ,it also goes wrong without current value. can you help me ? thanks.
@yang xk, it should be possible---in fact, this is (approximately) how the fpid_optimize function works; however, a more full description of your setup would be needed. Please send me a support request via e-mail, or, if you believe it's a bug, leave an issue report on GitHub.
hi, i want to design the fuzzy fractional PID using this toolbox,but i encounter a problem .
that is used s-function can't modify Fractional controller paramer(Kp,Ki,Kd,lambda,mic).
but it can worked using the same method modify the PID controller.
Create scripts with code, output, and formatted text in a single executable document.
