| 摘 要： | 基于一类线性系统的圆盘极点配置问题,提出了系统不确定项容忍区间的概念.利用系统不确定项单一偏差模型,给出了圆盘极点配置不确定项容忍区间的算法.系统设计者可以依据各不确定项的增益容忍区间,判断出各不确定项对闭环系统极点变化的影响程度,在工程设计中,根据其影响程度既可以降低设计的保守性来减少能源的浪费,同时也可设计出具有较高安全性能的系统.

| Abstract: | Based on a class of linear systems with relation to the disk pole placement,we have put forward the concept of uncertain linear system. With the uncertainty of single error model,we present the algorithm of the uncertain linear system tolerate interval in disk pole placement. System designers can determine the impact of the uncertainties in the closed-loop system poles placement,according to the tolerate interval of the uncertainty. In engineering design,according to the impact of the uncertainty,the conservatism can be reduced for cutting down the waste of energy,and the system with high security can be designed. |
