Other Parts Discussed in Thread: SFRA
Tool/software: Code Composer Studio
Hi ,
We have designed buck converter. And we are controlling the converter using TMS320F28069 launchpad.
So while searching I found that TI has given SFRA inside control suite. And I configured my program to communicate with SFRA GUI and it is connecting and i am able start small frequency injection on the duty to get the plants bode plot.
After confirming all sensing are proper in open loop. I have to complete the feedback loop that is Digital Compensator. But when i am using software provided by TI to get compensator coefficient and trying to run it it is not working.
So I have have lot of confusion about this software -
1. How can i ensure that i am getting correct plant model (Bode plot)?
2. what things i need to configure to work it properly?
3. To work it properly, how accurate sensing should be??
4. And as we know this is second order system , giving step change in input we could get transient response parameter. Is it possible to design compensator using transient response?
5. suggest me some link or documents so that i have to direction to close the loop.
Thanks
