I have been trying to work through a problem and see how its done but Im not sure where the angles of 17.10 -138.52 -109.84 = -231.26 come from.
I have attached the matlab root locus plot and the plot from the example also the ZOH transfer function is there and the dominant poles.
I printed it out and plotted the dominant poles but the angles didnt add up to -231.26
Can anyone suggest why and what Im doing wrong?
