    The latest version is 0.41-beta. The next version should be out by the end of the year.

    Dear Alekesi,

    In tuning using toolbox, using Z-N methods, for different transfer functions, it is showing same results.

    Do we have to do something before using Z-N method? (I have also tried to identify the model in FOPDT form).

    Thanking You,

    Dear pritesh,

    This should not happen. Please be more specific about how you obtain the above mentioned results.

    Dear Asif iqbal,

    Delta domain is not (directly) supported yet.

    sir is it possible to design a fractional controller in delta domain.

    Hello Aleksei,

    Thank you for the forum. Would you please guide me on using the Simulink blocks which are in the models folder of FOMCON? I want to use fractional order derivative and integrator in my Simulink, but I do not know how I can use it. When I open one of them there is a LTI model block in that and there is no other option to change the order. However, I only want to change the fractional order of them. It would be my pleasure if you kindly please guide me.

    Regards,

    Double click on the masked block to change its parameters. In case you were wondering, it is possible to do this programmatically as well.
    If instead of getting to the parameters you see the inside of the block, then you have a weird version of MATLAB (circa pre-R2010a).

    Dear Aleksei
    Many thanks for your valuable reply.

    I use MATLAB R2011a. However, when I open the fractional integral or fractional derivative blocks, I see a “LTI System” and a “Transfer Fcn1” block. When I open the “LTI System” block, which is a masked block, the only parameters that can be seen are “LTI System Variable” named as “G1” and “Initial States”, which is named as “[]”, but for the derivative or integral I only require changing their order. It would be my pleasure if you kindly please guide me on this problem. How can I change the order in the block or through the program?

    Is this problem related to the MATLAB version, which I use? Would you please guide me about the solution?

    Yours sincerely,
    Khoshnevisan
