Hybrid fuzzy-PI neural networks control with feedforward compensator for three-phase voltage source rectifier

Two-loop control based on a kind of neural networks current inner-loop and hybrid fuzzy-PI voltage outer-loop is discussed in the paper. As far as three phase voltage converter system is concerned, the control of neural networks makes it more strongly robust, hybrid fuzzy-PI accelerate the response of system. To improve the antiinterference of system, the current feedforward compensator is added. TMS320LF2407A that is the up to date production of TI Company is adopted to fulfill the entirely digital control. The simulation and experimentation result show the method is very effective.
