Just use fomcon

Do following things steps by step

1. Define your plant model in transfer function using tf command in matlab.

2. Convert same system in fractional transfer function object using fotf command. (Assuming that you have already added FOMCON in set path of your MATLAB)

3. open fomcon. (Type fomcon in your command window)

4. Go to Tools and select ‘Fractional PID Design’.

5. Go to Tuning tab and select ‘optimize’.

6. Defined constraints and other options as per your requirement.

7. Say optimize and wait for optimization

8. After sya, Take Values

9. Do simulate in Fractional PID design window
