本文探讨了根轨迹的相交特性,提出了判别在交点处闭环极点数的方法,给出了在分离点处有l条根轨迹相交时计算会合角和分离角的公式。
This paper discusses the intersecting characteristics of root locus and proposes a method to determine the number of closed-loop poles at the intersection point. The formulas for calculating the meeting angle and the separation angle at the intersection of l root points are given.
