Textbook Question
Chapter 8, Problem 9P
Figure P8.5 shows open-loop poles and zeros. There are two possibilities for the sketch of the root locus. Sketch each of the two possibilities. Be aware that only one can be the real locus for specific open-loop pole and zero values. [Section: 8.4]

The open loop transfer function of a humanoid's arm control system is given as:
K
G(s) =
2
s(s + 2s + 2)
(a)
Clearly locate all poles and zeros on a linear graph paper. Provide calculations for
the following: asymptote angles, centroid for asymptotes, and departure angle from
complex pole.
(b)
Plot the complete root locus, with the locus on the real axis is clearly shown. Use
the scale of 4 cm : 1 unit for both axes and choose the longer side of the graph
paper as the real axis.
Figure Q5 shows the root locus diagram of a system. From the figure, calculate the open-loop transfer function of the system.
One extra piece of information you require is that if the open-loop system is subjected to a sudden (step) change in input, then the output settles down at 2.5 times the input step size.
draw the root locus clearly, no handwritten and copied solution plz.
