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

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,
Khoshnevisan
