I am trying to use the two phase DC/DC controller software using F2808. I have a question regarding in CCS regarding the control co-efficients. I have my power stage transfer function converted to z domain but my co-efficients are in 100s. for example 100z^-2 + 200z^-1 + 500. Now the co-efficients in the program are in Q26 format, and it is given that the P,I,D values are only from 1-1000. How can I express the co-efficients I am getting in the software, can I decrease the Q value? Some help please.
