Hi all hope someone can help me here.
My problem involves the transfer function
As far as im concerned the centroid is calculated using
σ_a= (Ʃpoles - Ʃzeros) / (# of poles - # of zeros)
From my calculations
However when i input the following code into MATLAB the solution from the graph shown the centroid will be -1.55
s=tf('s'); G=(s+32.8)/((s+2.8)*(s+5)*(s+27.8)); rlocus(G)
Im not 100% whats the issue but if im doing something wrong could someone please correct me and help me understand.
Thank you for taking your time out to read this.
