摘要: This study deepens on the transient response analysis of so-called vector proportional-integral (VPI) controllers and compares them with popular proportional-resonant (PR) for grid-connected applications. The employed methodology is based error signal roots: both reference tracking disturbance rejection abilities are considered proper gain tuning. proves that PR lead to shorter settling times than VPI controllers. A three-phase voltage source converter prototype has been implemented. Experimental results comparing behaviour in different conditions provided: a + 90° phase-angle jump current `type C' sag at point common coupling.
