Multiple choice

A plant transfer function is given as G(s) = $\bigg(k_p + \frac{K_i}{s} \bigg) \frac{1}{s(s+2)}$. When the plant operates in a unity feedback configuration, the condition for the stability of the closed loop system is

  1. $K_P > \frac{K_I}{2} > 0$
  2. $2K_I > K_P > 0$
  3. $2K_I < K_P$
  4. $2K_I > K_P$
