| 中文摘要 |
| 为解决PI矢量控制动态响应慢且依赖电机精确参数的问题, 本文将滑模控制与空间矢量调制结合, 提出了一种开关频率固定的滑模直接电压控制(SMDVC)方法, 以实现双馈感应电机(DFIG)的电网同步控制. 实验结果表明, 提出的SMDVC方法具有比PI矢量控制更好的动态性能, 即使在电网电压不平衡工况下, 也能较好地控制DFIG定子电压实现对电网电压的精确跟踪. |

| To handle the slow dynamic response and the dependency on accurate machine parameters in PI vector control, we propose a sliding-mode direct-voltage-control (SMDVC) with constant switching frequency to realize the gridsynchronized control for the double-fed induction generators (DFIG). Experimental results show that the proposed SMDVC method is with better dynamic performance than the PI vector control; it can effectively control the stator voltages of DFIG to accurately track the grid voltages under imbalance conditions. |
