标题[讨论] 自动控制Root-locus疑惑?
时间Mon Dec 10 01:11:14 2012
Dear 大大们
小弟自控要用Matlab验证求解,题型如下:
A unity feedback system has a loop transfer function of
G(S)=K(S+2.5) / (S^2+2S+2)(S^2+4S+5)
Draw the root-locus plot of the system for 0<K and find the gain K resulting
in dominant roots with a damping ratio of 0.6 ?
小弟不懂的是,damping ration 0.6 跟 root-locus 有什麽样的关系存在
谢谢
