In this paper a proposed control strategy based on fuzzy logic for three-phase PWM rectifiers is discussed. This technique is called direct control of fuzzy power (DPCF). The objective of this paper is to substitute both hysteresis controllers of the active and reactive power by a single fuzzy controller which adjusts both active and reactive power at the same time. The aim of this work is to eliminate...
A direct power control (DPC) scheme for three-phase PWM rectifier based on sliding-mode variable structure control theory is presented. Compared with the traditional PI controller, the proposed scheme is much more robust with better transient performance, lower total harmonic distortion (THD) and simpler tuning of parameters. Modeling and simulation done in MATLAB/SIMULINK environment shows that the...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
