Need help implementing MATLAB-based P&O MPPT algorithm on a microcontroller for PWM generation and integration with a DC-DC buck converter design.

I’ve written a MATLAB function for the Perturb and Observe (P&O) MPPT algorithm and want to implement it on a microcontroller. The goal is to use the algorithm to generate a PWM signal for controlling a DC-DC buck converter. However, I’m having trouble finding resources or examples for integrating the MPPT algorithm with the microcontroller's PWM module and linking the microcontroller to my buck converter design on MATLAB. Any guidance, example codes, or best practices for implementing MPPT algorithms on embedded systems would be greatly appreciated.

Hi @Zeynep Deniz Gundogan,

As I see, you are looking for resources on MPPT algorithms. Here is a useful resource page for MPPT algorithms with example tutorials in Simulink:

Additionally, there is a useful File Exchange submission that links MPPT to a DC-DC boost converter using the Perturb & Observe method:

Here are useful links on best practices for Simulink modeling and hardware integration on embedded systems:
