The modern weighted fuzzy first maxima defuzzification technique for fuzzy control of vschvdc converters

Abstract EN

The new Weighted Fuzzy First Maxima Defuzzification method is propose, which will can easily provide much better performance in Fuzzy Control for VSCHVDC converters.

A comparative analysis of various, Defuzzification technique put into practice in fuzzy logic control such as Center of Area (COA), Center of Sum (COS), Middle of Maxima (MOM), and First of Maxima (FM), for VSCHVDC Converters is presented .The characteristics difference between different technique are outlined A new method called Weighted Fuzzy First Maxima is proposed and its performance is evaluated.

The paper also provides simulation outcomes of the performance.

The simulation shows that COA and COS Defuzzification technique have much better dynamic performance and less steady state error.

The new Weighted Fuzzy First Maxima system : Defuzzification technique offers further improvement.

In this Simulation result are compared with mathematical model and with Fuzzy Controller using the proposed defuzzification technique on multi-infeed HVDC on IEEE 30 bus system.
