SUMMARY

The discussion focuses on implementing a feedback system using a Linear Time-Invariant (LTI) transfer function on the TMs320F28x DSP to stabilize a DC-DC converter. The main challenge is converting the digital transfer function into code suitable for the DSP. Participants emphasize the importance of transforming the transfer function into a difference equation for easier implementation. The conversation highlights the need for online resources to assist with this conversion process.

PREREQUISITES
  • Understanding of Linear Time-Invariant (LTI) systems
  • Familiarity with the TMs320F28x DSP architecture
  • Knowledge of digital signal processing (DSP) concepts
  • Ability to formulate difference equations from transfer functions
NEXT STEPS
  • Research methods for converting transfer functions to difference equations
  • Explore programming techniques specific to TMs320F28x DSP
  • Learn about feedback control systems in digital signal processing
  • Investigate online resources and tutorials for DSP implementation
USEFUL FOR

Engineers and developers working on digital signal processing, particularly those focused on control systems and stabilization of power converters using the TMs320F28x DSP.

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:)
