最后基于经典控制理论的根轨迹法整定直流小信号调制器参数。

Finally, parameters of the HVDC small signal modulator are tuned based on root locus rules of the classical control theory.

而且，该方法易于用一般的机电暂态仿真软件实现，并可用于FACTS小信号调制器参数整定。

Also it can be employed to tune parameters of small signal modulators of FACTS. Furthermore, this method can be easily implemented by electromechanical transient analysis programs.
