Effect of addition of poles =>

i) Root locus shift towards right half of the s-plane

ii) system stability relatively decreases

iii) system becomes more oscillatory in nature

iv) range of operating values of k, for stability of the system decreases

Effect of addition of zeros =>

i) Root locus shift towards left half of the s-plane

ii) system stability relatively increases

iii) system becomes less oscillatory in nature

iv) Range of operating values of $K_1$ for stability of the system increases
