Question:
For the unity feedback system shown in Figure P8.3, where
do the following:
a. Sketch the root locus.
b. Find the range of gain, K, that makes the system stable.
c. Find the value of K that yields a damping ratio of 0.707 for the system’s closed-loop dominant poles.
d. Find the value of K that yields closed-loop critically damped dominant poles.
Transcribed Image Text:
K(s + 10)(s +20) 10s- G(s) = (s + 30)(s2 – 10 s+100)
