采用二阶滤波环节平滑速度指令，实现了理想无超调的快速速度跟踪控制。
A second order filter is used to smooth the speed reference signal, and the perfect non-overshooting speed tracking is achieved.
为此，提出了新的控制策略，该控制策略通过检测并消除指令中的零序分量，以破坏无零序电流回路系统的零序电压正反馈条件，消除DVR注入零序电压的不良影响。
So a new control strategy is proposed to detect and suppress the influence of zero sequence component injected by DVR. Simulation results show that the proposed strategy is co…
