How to do recursive least square for online parameter estimation

I have stucked in this details for months now

I have constructed my simulink model which is a little complicated (containing a PV array + DC/DC converter ) using simscape

the simulation is working for this first stage

The second stage is to use online parameter estimation to estimate the time varying parameter of the PV cell

i have the simulated data Pmpp and the experimetal data Pmpp

now i want to do it online to update comtimuosly the parameters

the problem is that most of the apps and blocks in simulink support using an Autoregressive models like ARX ARMA ...

But iwant to do it with my simulink model

Any help

You will need to describe your expectations for the response so that interested forum members know how they can assist you in the most meaningful way.

For example, would you be fully satisfied with individuals sharing links to tutorials and a list of self-study materials, allowing you to take your time to learn how to implement recursive least squares for online parameter estimation?

Dear Sam

My expectations is either to find the app or tool or prebuilt blocks that facilitates the use of this technique with a tutorial

or proposition for an other way to achieve my goal

I can share my model

i have found plenty of studies , but no study count on simulink model as estimated model

either they simulate models and obtain data and pretend as it is real or they import real data directly

and for the simulated model they use autroregressive models most of times amd regressors

and since i have my own simulink model and i have experimental data

do i have to switch to polynomials likem ODE or autoregressive or i can keep on with my simulink model for recursive online parameter estimation objective ?

@YASSER, Can you please provide the frequency with which the new data will be added or how the the new data is added.
