提出了一种基于虚拟磁链的新型协调控制策略，它通过负载功率前馈控制得到瞬时有功功率，然后利用功率误差产生整流器参考电压。该策略可有效抑制直流母线电压的波动，减少母线电容容值，降低控制系统的复杂性。此外，采用虚拟磁链可以解决控制系统的硬件成本和可靠性问题。

In this paper,a developed coordina-ted control strategy based on virtual flux was pro-posed.The instantaneous active power can be ob-tained by means of load power feed forward con-trol,and then the duty cycle of rectifier was calcu-lated by power error. This control strategy is proved to be effective on reducing the fluctuation of DC bus voltage and the value of bus capaci-tance,simplifying the control system.In addition, virtual flux can solve the hardware cost and control system reliability issues.
