Buck with pid microcontroller in matlab environment

Click For Summary

Discussion Overview

The discussion revolves around the design and implementation of a PID microcontroller for a buck converter circuit within a MATLAB environment. Participants are exploring the modeling of PID control loops and the integration of these concepts into their final year projects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant seeks help with modeling a PID microcontroller and its design in MATLAB for their final year project.
  • Another participant questions the original poster about their learning resources and experience with PID control loops and MATLAB, emphasizing the need for independent work.
  • A participant expresses confusion about how to design a PID microcontroller from a buck converter circuit, indicating a lack of direction.
  • Another reply clarifies that a PID control loop differs from a buck DC-DC converter control loop and questions whether the intent is to control the converter with a PID program on a microcontroller, highlighting the need for a fast microcontroller or a slowly responding converter.
  • Participants inquire about the specifications and goals of the project to better understand the requirements.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are differing interpretations of how to integrate PID control with a buck converter, and the discussion reflects uncertainty about the project requirements and design approach.

Contextual Notes

There are limitations in the clarity of the original question, particularly regarding the relationship between PID control and buck converter design. The discussion also lacks specific details about the hardware and specifications involved in the project.

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?
