摘要: 本文提出了系统特征系数灵敏度的概念,导出了特征系数灵敏度与特征值灵敏度闻的关 系.在此基础上,提出了一种以加权特征系数灵敏度为性能指标,结构化小参数摄动下的鲁 棒极点配置控制系统的设计方法.特征系数灵敏度计算简单,目标函数的极小化采用标准的 具有二次收敛性质的参数最优化方法.Abstract: A new concept, characteristic coefficient sensitivity, is introduced. The relationship between it and eigenvalue sensitivity is also given. Based on these, a new method for designing robust pole assignment control systems is established with characteristic coefficient sensitivity as its cost functional. Owing to its advantage of avoiding both the calculation of eigenvalue sensitivity and the assignment of eigenstructure, this procedure is quite simple and can be programmed on a digital computer.
