Hi
I am presently working on TMS320F28069. please tell me, How can we calculate the co-efficient values of 2-pole 2-Zero control system ?.

Hi!
If you mean ti\controlSUITE\libs\app_libs\digital_power\f2806x_v3.4\Doc\DPLib.pdf (chapter 5) then for the synthesis and analysis of digital filters you can use MatLab. MatLab allows to calculate the coefficients of the discrete transfer function on the set the poles and zeros, and vice versa.

Hi Igor Gorbachev,
Thanks for your reply.
I installed controlSUITE in my PC but i did't find a folder ti\controlSUITE\libs\app_libs\digital_power\f2806x_v3.4 in my PC.
Please can you tell me where you find that file, give me the URL link.
Thanks & Regards

Hi Guys,
As Prashanth mentioned, even I don't have f2806x_v3.4 directory in controlSuite.
Prashanth, instead what you can do is read the theory from any other family's DPLib.pdf and try implementing it for f28069.

Hello,
The following post has a pre-release of the f2806x DPlib. You may find it useful:

Thank you,

Hi Prashanth!
All this is very strange. I have the last version of controlSUITE. Here is the lost folder 0257.f2806x_v3.4.rar. Place it into ti\controlSUITE\libs\app_libs\digital_power\ for orderliness.

Igor
Hi Igor Gorbachev,
Thanks for your reply.
I downloaded f2806x_5F00_v3.4.rar folder. In the documentation of DPLib, mention that this library applicable to only 32-bit fixed point processors. But f28069 has a 32-bit floating point CPU. So this library is not applicable to f28069. Please give me link, if you have Digital library for f28069 32-bit floating point CPU.
Thanks & Regards

Hi Prashanth!
I'm sorry. You are right. I found the contents of my folders f2806x_v3.4 and f2803x_v3.4 are identical absolutly. I don't know how the folder f2806x_v3.4 has been generated (these are some glitches). Indead this is the fixed point DP library. There is the floating point DP library for F28M35 only Into folder ti\controlSUITE\libs\app_libs\digital_power\. Try to request TI about the floating point DP library for F2806x (asktexas@ti.com) or you can try to use what mentioned by Brett http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/277005.aspx?pi177899=2 (3276.F2806x-DPLib_Template.zip).

I'll add a few additional thoughts based on my understanding:
1) I am not aware of a F2806x DPlib that was ever released through controlSUITE.
2) The Prerelease-F2806x DPLib that I attached in the other forum thread only uses fixed-point math.
As Igor describes, using the F28M35 DPLib as a reference for floating-point may help.
Thank you,
Brett
