Using the proposed switch control strategy to track the references, load voltage and current are compensated.
利用上述的开关策略进行跟踪，达到对负载电压和电流补偿的目的。

The voltage and flux errors at the sampling instant can then be compensated for in the next control period, so the errors are always kept small, which leads to small fluxes and torque ripple.
Direct current control method is adopted to make the DSTATCOM produce compensated reactive current, so as to suppress voltage fluctuation and voltage flicker.
