Implementation of Fuzzy Logic Controller on DC-DC Buck Converter: Matlab Simulation (Part 2)

[@ASeriousCircuit]

Link to the Matlab simulation files (Implementation of Fuzzy Logic Controller on Buck, Boost, and Buck-Boost), and link for the videos on basics of the fuzzy logic toolbox in Matlab are given in the description.

Thank you very much, great work Move forward ,May ALLAH bless you🌺

can you make your paper access to us so that we can read it deeply

[@ASeriousCircuit]

Hiii @@saitejasalveru7830 sorry but IEEE holds the copyrights, so I can not make it public.

[@yeddu495]

nicely done ,sir you have fuzzy logic control for Dual active bridge

[@ASeriousCircuit]

Thanks Dinakar! Sorry I have not worked on that.

how to decide the range of error & change in error ( membership function) ???

[@ASeriousCircuit]

Generally, It is good practice to keep maximum range equal to 1 and scale the segments (PB, PS, Zero, NS, NB) accordingly. For example , if you have desired output Vout = 18 volt and when you output is from 17 volt to 19 volt you want to call it zero error, then in membership function keep you Zero function from -(1/18) to (1/18) because according to scaling 1 is at (18/18), and -1 is at -(18/18). This is just one way to do it you can scale according to your requirement .

Great Video! Can we use the same logic table for a boost converter?

[@ASeriousCircuit]

Thank you! Yes we can use the same for buck, boost, and buck-boost. I have uploaded controlling for all three converters.

Sir what is the relationship between error and change in error, and how did you come to the conclusion when error value is NB and change in error value is PS the output should be PS ??

[@ASeriousCircuit]

I don't understand what do mean by relationship between error and change in error. Error simply means (reference - desired output). Change in error = (Error at time t - Error at time t-1). Why have I taken output as PS (for NB and PS) these decision depend on the property of your system. The busk converter acts in a way that when error is NB and change in error is PS the control signal must be PS to decrease the error. Hope it gives you clarity
