In order to overcome the difficulty in estimating the ripple component on dc-side capacitor reference voltage, the modified control algorithm is proposed by ignoring the ripple component. Furthermore, the relation between control performance and damping coefficient is researched. In addition, the reasons of voltage source converter inner-loop control overmodulation are also analyzed. Based on the relation between control performance and VSC inner-loop input saturation, damping coefficient is adjusted on-line by fuzzy logic reasoning so that the trade-off between control accuracy and limitation of VSC inner-loop control overmodulation is solved preferably.
