Transcribed Image Text:S2
Sketch the loci diagrams and calculate the gain for (a) critical damping and (b)
a damping ratio of 0.6 for a system having an open-loop transfer functions of :
K
KGH = s(s + 1)
A control system is represented as the block diagram shown below:
S3
R(s)
C(s)
K
s(s +4)(s+6)
Draw the root locus of the closed loop system. Determine a roots for the operation
point, s, when = 0.5 Also at this point, determine the natural frequency, om
damped natural frequency, ws, and the value of K.
