[討論] 自動控制Root-locus疑惑?
Dear 大大們
小弟自控要用Matlab驗證求解,題型如下:
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 有什麼樣的關係存在
謝謝
