MATLAB Buck with pid microcontroller in matlab environment

AI Thread Summary
The discussion centers on designing a PID microcontroller for a final year project, specifically in relation to a buck converter circuit. The individual has a basic understanding of PID control but is unsure how to apply it to their specific project. Key points include the need for clarity on whether the goal is to control a DC-DC converter using a PID program on a microcontroller, which requires a fast microcontroller for effective performance. Participants emphasize the importance of understanding the specifications and requirements of the project before proceeding. There is also a suggestion to utilize learning resources and ask specific questions after conducting preliminary research to gain a better grasp of the topic.

What are you doing to learn more about PID control loops? What learning resources are you using? What microcontroller are you going to be working with? What clock rate and hardware resources are you planning on using? How long have you been using Matlab, and what are you doing to learn more about it?

You will need to do the bulk of the work on your own. You are welcome to ask specific questions here after you have done your homework. Welcome to the PF!
 
i already study the basic of PID. the problem is ,how to design the PID microcontroller from my buck converter cct..? where or what i must begin with..? i totally lost here

Your question is confusing. A PID control loop is different from a buck DC-DC converter control loop. Or are you saying that you want to control a DC-DC converter with a microcontroller running a PID program? That's going to have to be one FAST uC, or else one slowly responding DC-DC...

What are the specs of what you are trying to achieve?
