摘要
This paper proposes a model-free predictive current phasor control for three-phase grid-connected voltage source converters. The control method regulates the grid current vector magnitude and phase with respect to the grid voltage vector in a stationary reference frame. The method inherently enjoys a fast transient response and high-power quality with a low sampling frequency. It avoids any system model information in the control algorithm for current vector prediction. A direct and effective current limitation routine is embedded into the control algorithm. The method features a simple control structure and low computation burden. It lacks any pulse-width modulation sub-system, additional sensor, lookup table, state observer, and grid voltage and current transformation. The proposed method is evaluated through simulation studies, where the results illustrate the effectiveness of the method and its superiority over conventional methods under the parameter mismatch conditions.
