摘要
本文给出了闭环系统根轨迹存在分离点的充分必要条件。研究表明,根轨迹的分离点可位于复平面上的任意位置,而且阶次是任意的。利用该充分必要条件,可以构造使闭环系统根轨迹包含分离点的被控对象传递函数。
A necessary and sufficient condition which the root locus of the closed-loop system contains breakaway points is obtained. The study shows that the breakaway points can bc located everywhere on the complex plane, also the order is arbitrary. Using this condition, the transfer function of the plant is derived which the root locus of the closed-loop system contains breakaway points.
