Application of fuzzy logic algorithms for harmonic elimination and voltage control in a PWM waveform

Abstract

This paper describes a new method for the elimination of harmonics and analysis of PWM waveforms using multivariable fuzzy logic algorithms. A multivariable fuzzy system has been developed to model the nonlinear equations in the analyses of PWM waveforms, and to eliminate certain harmonics. The results show that the proposed fuzzy method introduced outperforms many numerical techniques applied to solve the nonlinear equations required in Fourier series harmonic elimination.
