    Hello fellow users,

    I'm doing a project at uni in the area of maximum power tracking of PV systems using Simulink.

    Basically I've managed to design the PV array, lossless Dc-Dc converter and to a certain extent MPPT. The converter is a buck-boost containing no electrical elements except for controlled v and i sources, small resistive load of 10 ohms and a function block which computes the input current to the coverter. The other parameters Vout, Vin, Iout are all determined through the feedback loops.

    The mppt outputs a reference voltage signal which obviously needs some sort of compensation. This is the part I'm struggling with. Some past students have hinted that PID controller is a good way to go.

    Any suggestions/advice would be fantastic as the summer break gradually becomes a working holiday by the week.

    Thank you all!

    I guess he got it sorted and went back to uni in March so he'd be flat out now

    Its a modelfile for Simulink I suppose
    here it is in text form but I don't think that's of much use to anyone

    PV_Array_with_mppt

    Dear Sir\Madam,
    I have downloaded this file unfortunately after the running in the SIMULINK I have faced with some of errors. Please let me know whether there is any problem in this project or not.
    If you have similar program about photovoltaic simulation I will be gratitude if you can send to me to my email m_marzband2005@yahoo.com
    Thanks a lot in advance for your attention
    Best regards,
    Mousa Marzband
