A. 4 and (-4,0)
B. 3 and (-12,0)
C. -4 and (-4,0)
D. -3 and (-12,0)
Answer:A
The open loop transfer function of the feedback control system is given by G(s) =K(s+3)/s(s+4)2(s+5)(s+6). The number of asymptotes and the centroid of asymptotes of the root loci of closed loop system is
A. 4 and (-4,0) B. 3 and (-12,0) C. -4 and (-4,0) D. -3 and (-12,0)
Explanation: Number of Poles = 5
