Abstract :
The current state feedback decoupled control strategy in the synchronous reference frame is generally used for the three-phase voltage-source PWM rectifier, which lies in the precise inductance measurement value. In this paper, the effect of the systempsilas performance with the varying of the inductance measurement error and the synchronous frequency is investigated, and the current error feed-forward decoupled control strategy is presented, comparative analysis indicates the fact that this strategy is not sensitive to the inductance and the synchronous frequency. Finally, results of the system simulation and experiment by using the mentioned strategy are presented.
