Root locus of s(s+2)+K(s+4) =0 is a circle. What are the coordinates of the center of this circle?
Root locus of s(s+2)+K(s+4) =0 is a circle. What are the coordinates of the center of this circle? Correct Answer -4,0
s(s+2)+K(s+4) =0 1+K(s+4)/s(s+2) =0. G(s)H(s) =K(s+b)/s(s+a) Centre =(-b,0) =(-4,0).
