@Aleksei Tepljakov Thanks a lot for your very helpful contribution, I have already cited you in my last paper. However, I am experiencing an instantaneous/transient shattering "100 times the original signal" in the first 2 seconds of running the Simulink model with the fractional derivative while the rest of the simulation period is reproduced fine, any idea how to solve this?
@jegajothi balakrishnan you need to add the file to the toolbox location located in the Matlab installation as follows: C:\Program Files\MATLAB\R2017a\toolbox\fomcon then go to MATLAB and add to path selected files with subfolders simply by using the command "Pathtool"

Any one can give answer for my error?
In my model it shows some error that failed to load library block FO/PID

Dear sir,
Could you mind to show me how to programmatically tune the fractional order number (gamma) in the fractional operator? I tried using the 'set_param' function in a MatlabFunction Block to tune this parameter during the simulation, but it did not work at all.
Thank you.

In matlab coding i have a problem. When i try to code like following, i came across the fault. In PID control there is no problem like this. Can you guess where problem is? Thank you very much.

Dear prof Aleksei
I am using the FOTF Veiwer gui. When I add my TF all the options work correctly but when i want to export system as a oustaloup zpk or oustaloup refined filter zpk it doesnt work and "Erroneous model, export aborted: possibly due to too high order of approximation" error comes up but my order is 5.
I would appriciate it if you help me

Dear Prof Aleksei
I have already used FOMCON but now it's showing the error "Initialization commands cannot be evaluated.
Caused by: 'config' is an invalid option". I need your help Sir. i also try to reach FOMCON website. i am working in modelling of fractional order systems if you can share your idea it will very helpful for us.

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 Although the FOMCON website is no longer actively maintained, the information provided there can still be useful.

Dear Prof.
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.

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)

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.
