一类线性输出反馈控制器，分配一组所需的自共轭特征值的闭环系统最近的参数化，制定和解决的基本响应不灵敏度问题。它是建立在何种程度上输出反馈控制可以用来使闭环系统的响应不敏感可能有许多不一定小的参数变化，在开环状态空间模型。一个非保守的顺序设计过程中，尽可能多的闭环系统的本征模完全不敏感，同时保持任意分配的最大数目的闭环特征值。主要结果是一类灵敏度降低的固定增益输出反馈控制器明确指定的一组自由参数，可以选择，以满足额外的设计要求。条件给出了总模态解耦不灵敏度可能有许多不一定小的参数变化的开放式L…
A recent parameterization of the class of linear output-feedback controllers that assign a set of desired self-conjugate eigenvalues to the closed-loop system is used to formulate and solve a fundamental response insensitivity problem. It is established to what extent output-feedback control can be used to render the closed-loop system response insensitive to possibly many not necessarily small parameter variations in the open-loop state space model. A non-conservative sequential design procedure is developed for making as many of the closed-loop system eigenmodes as possible totally insensitive while retaining arbitrary assignment of the maximum number of closed-loop eigenvalues. The main result is a class of desensitizing fixed-gain output-feedback controllers explicitly specified by a set of free parameters which may be chosen to satisfy additional design requirements. Conditions are given for total modal decoupling insensitivity to possibly many not necessarily small parameter variations in the open-l...
