英文摘要：
The delay induced by zero-order-hold and computational time affects the dynamic performance of active power filter. In order to improve the dynamic performance of current tracking, a new dead-beat current control method based on voltage space vector for active power filter was proposed. This method determines the reference voltage space vector by using dead-beat current control algorithm. And together with voltage space vec- tor control method, the reference current can be tracked quickly and accurately, and this method is effective in restraining the effect of system voltage wave on compensating performance. The validity and feasibility of this current control method has been testified with simulations and experiments.
