Direct Power Control Strategy of PWM Rectifier Based on Improved Virtual Flux-Linkage Observer by Wenshao BU, Leilei Xu

“…Then, in order to avoid the effect of integral initial value and cumulative deviation, three first-order low-pass filters are cascaded to replace the pure integral link; an improved virtual flux-linkage observer of three-phase power grid is presented. From the observed virtual flux-linkage, the voltage and instantaneous power of three-phase power grid are online estimated. …”
