Hello,
I have a problem with an MPPT model using fuzzy logic: the method doesn't work as the output duty cycle is always zero, thus the output power is not even close to the MPP and i am sure that i correctly implemented all the blocs of the model (PV module, boost converter,...) as well as the fuzzy logic membership functions.Can any one help? i have joined the images of the model i'm using, the mppt bloc and a subsytem i'm using inside.

did you resolve the problem? I am using PYO MPPT model, but does not work too, the voltage step down and I am using a Boost, if I don´t use the MPPT model the boost high the voltage.

Hello, can anyone answer on how to find the membership values of input and output. I mean universe of discourse (UOD). Thank you
