摘要
根轨迹法是自动控制原理课程中的一种重要分析方法。对于高阶系统,课堂上难以根据绘制法则绘制精确的根轨迹图形。利用matlab界面编程技术实现了各阶系统根轨迹的动态绘制,绘制过程中通过点击按钮实现暂停和继续,有助于学生对根轨迹概念的理解。最后给出二阶系统和三阶系统的根轨迹图形,验证了系统结果的正确性。
The root locus method is a kind of important analysis method in the course of automatic control principle. For high order system, it is difficult to precisely draw root locus figure according to the mapping rule. In this paper, matlab GUI technology has been used to achieve the root locus＇ dynamic drawing,which is beneficial to the students＇ understanding of the root locus＇ concept. Finally, the root locus of second order and third order system are given, which verifies the correctness of the system results.
