系统函数的表示法及与响应的关系 稳定性判据(含反馈系统) 频响的矢量图解

一、引言与准备 1、循环关系 欲求介质中E→则需E∵E=E+E需p需 (p.ds=-q,或p=-V.P、o=Pn)需知EP=oxE),返 回,出现循环。 表明:极化原因(E:自由电荷激发的外场、E:总场)和极化效果(E :由束缚电荷q激发)之间有反馈联系

Weighting Matrix Selection a good rule of thumb when selecting the weighting matrices Rxx (or Ru and R uu is to normalize

Bounded gain There exist very easy ways of testing(analytically) whether S Gu)< SISO Bounded Gain Theorem: Gain of generic stable system

Full-state Feedback Control How do we change the poles of the state-space system? Or, even if we can change the pole locations Where do we put the poles? Linear Quadratic Regulator Symmetric Root Locus How well does this approach work? Copyright [2001 by JOnathan dHow

This is a bit strange, because previously our figure of merit when comparing one state-space model to another(page 8-8)was whether they reproduced the same same transfer function Now we have two very different models that result in the same transfer function
