| 摘 要： | 采用根轨迹法校正高阶系统时，应当使校正后系统的根轨迹与期望主导极点适当接近，但不一定越近越好；不仅要求校正后根轨迹接近期望主导极点，还必须注意到校正后系统的非主导极点与主导极点的位置关系；还应当使接近点位于阻尼角45°线附近；为了动态过程尽快结束，应使闭环极点间距取大，零点靠近极点；校正装置中的零点与固有系统中某个极点重合是行之有效的．

| Abstract: | When adopting the locus correction method to calibrate the high- order system, the root- locus of corrected system ought to be suitably close to the expected closed loop dominant polar, yet not too closely; at the same time, the close point ought to be bring the dynamic process to an end as quickly should be greater, the zero point is near to the some polar in the original system is effective. placed near to the damping as possible, the intervals polar; coincidence of zero degree of the point o of 45 string; in order to closed loop polar points f corrected system with
some polar in the original system is effective. |
