Discussion Overview

The discussion focuses on the implementation of a feedback system using a linear time-invariant (LTI) transfer function on the TMs320F28x digital signal processor (DSP). Participants explore the challenges of converting a digital transfer function into code suitable for the DSP.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks guidance on implementing a feedback system using an LTI transfer function for a dc-dc converter on the TMs320F28x DSP.
  • Another participant questions whether the issue lies with the specific DSP or the conversion of the digital transfer function into code.
  • A later reply clarifies that the main problem is converting the digital transfer function into code.
  • One participant suggests that converting the transfer function into a difference equation could simplify the implementation process and requests the specific transfer function for further assistance.
  • A subsequent response indicates that the participant feels confident in implementing the solution independently after understanding the suggestion.

Areas of Agreement / Disagreement

Participants express differing levels of confidence regarding the implementation process, with some seeking assistance while others feel capable of proceeding without further help. The discussion does not reach a consensus on the best approach to the problem.

Contextual Notes

The discussion does not provide specific details about the transfer function or the exact challenges faced in the implementation process, which may limit the applicability of the advice given.

Helo,
I am currebtly working on a dsp, in a goal to implement a feedback system in the form of an LTI tranfer function that will stabilize a dc-dc converter.
The problem is as follows:
We have the digital desired transfer function, and the problem is how to work with the dsp for impelmentaion on the dsp.
We are lookng for materail on line that will help us do that.
our dsp is:TMs320F28x.
Thx

Is your problem related to your specific DSP, or how to convert your digital transfer function into code?
 


how to convert the digital transfer function into code.
this is the problem.
exactly!
 


If you can convert the transfer function into a difference equation, this should be pretty easy. If you need help, can you provide us with the transfer function?

thanks kerry
i understand what you are saying...this is not tough to implement on the DSP i can figure it out for myself

cheers:)
