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

According to smallsignaltheory of automation theory, arc of low current TIG welding can be considered as a linear system.
依据自动控制理论中的小信号理论，小电流TIG焊的电弧具有线性系统的特征。

Discrepancies which have long existed between theory and practice concerning the prediction of dynamic instability of a VSI drive by the smallsignaltheory are resolved.
