Hello ! I am generating a Vmpp using a Neural network and want the MPPT to output Vdc equivalent to this Vmpp. For this purpose I need to input a duty cycle into the Boost converter. I am using the formula d=1-(Vdc/Vmpp) But the duty cycle does not follow this formula and takes the value of the duty cycle to 1 (it always maxes out). Kindly guide me if I am using the right technique to control the Duty cycle or not

Yeah, the problem here is you're measuring Vdc incorrectly.
Vdc isn't the measured DC link voltage on the output side... it's the DC voltage at the source (PV Array) on the left side of the boost converter.

I am building a Buck DC DC Converter but interfacing Neural Network Subsystem and the Converter is my challenge.
Please can anybody assist?

Hi,
I am really confused on how to create a custom neural network. Should I build it using neural network toolbox first then import or build while in simulink. Need help guys urgently.
Thanks

Hello Haider,
Please I want to interface my Neural Network Subsystem with my Buck Converter but the setting of the parameters in the Simulink is my big problem.
Please could you assist me?
