Abstract
This paper proposes a new discrete fuzzy-tuning current-vector
control (FTC) scheme for three-phase pulsewidth modulation (PWM)
inverters. The proposed current control scheme can achieve fast
transient responses and, at the same time, have very low total harmonic
distortion in output current during steady-state operation. The proposed
FTC scheme generates quasi-optimum PWM patterns by using a closed-loop
control technique with instantaneous current feedback. The proposed FTC
scheme has been realized using a single-chip digital signal processor
(TMS320C14) from Texas Instruments. Experimental results are given to
verify the proposed fuzzy-tuning current control strategy for
three-phase PWM inverters
