We know that the root loci start at the poles (for K = 0) and end at the zeros (for K = o) of P(s). Also, we know that the root loci are on the real axis to the left of the odd numbered poles and zeros. Put the following characteristic equation in the correct format for drawing the root loci. (1 + K)s + (2K + 3)s + 2 3K = 0 Obtain the root locus plot for using MATLAB. The following expression gives what polynomial? I is the identity matrix. |SI - A =?
