fuzzy MPPt

I am currently simulating a MPPT for solar cell connected to buck converter where the duty cycle is being controlled by a fuzzy logic controller. Now, the fuzzy logic controller inputs are my error E = P(n) - P(n-1)/v(n)-v(n-1) and change CE=E(n)-E(n-1)

but when connected to fixed load it give error E is divided by zero

Answer 1

please explain more... you are doing MPPT in simulink or function mode? and what is the input of MPPT? I and V or just I or V?

Answer 2

Mahmoud ,Could you connect your PWM to DC/DC converter?

Answer 3

u can opt out for a ordinary controller

[Walter Roberson]

I do not understand what you mean by "opt out" in this context?
