Dear Manish,

You said the PR controller was topic of research last year, now I'd like to ask if you have developed it?

Thank you and looking forward to have your feedback soon.

Best regards,

Felix

Felix,

You can map the PR controller to a generic 2p2z structure which is available in solar library,

I am attaching my work for these equations, feel free to check and comment5556.PRcontrollerMappedto2p2z_Pg1.pdf 1273.PRcontrollerMappedto2p2z_Pg2.pdf...

Hi Manish,

Thank you! I'm trying to work out the coeff's now. I worry about the sensitivity to the resonant frequency (like 50Hz, w=628), the coeff_A1 = -2*(w2-1)/(w2+1), but in the fact the portion (w2-1)/(w2+1) is basically 1, so the coeff_A1 may be always -2, is this a problem?

In addition, is the sampling frequency a important factor to the resonant controller? that is not mentioned in the PDF you shared.

Thanks!

Felix
