GATE ECE 2018 | Question: 42

Question

The figure below shows the Bode magnitude and phase plots of a stable transfer function $G\left ( s \right )=\dfrac{n_{0}}{s^{3}+d_{2}s^{2}+d_{1}s+d_{0}}.$

Consider the negative unity feedback configuration with gain $k$ in the feedforward path. The closed loop is stable for $k < k_{0}.$ The maximum value of $k_{0}$ is _________.

Answer 1

this question is wrong as in the question it is given bode plot of the stable system is given ,but here in the plot the gain margin is negative,so the system cannot be stable.So,i think after challenge this question will be cancelled

okay. Lets wait.
