- The figure shows a closed-loop system with a plant \(G(s) = \frac{1}{s^2}\) and a lead compensator \(C(s)\). The compensator is designed to place the dominant closed-loop poles at \(-1.5 \pm j\frac{\sqrt{27}}{2}\). From the following options, choose the phase lead that the compensator needs to contribute.

Consider the control system block diagram given in Figure (a). The loop transfer function $G(s)H(s)$ does not have any pole on the $j\omega$-axis. The counterclockwise contour with infinite radius, as shown in Figure (b), encircles two poles of $G(s)H(s)$. Choose the correct statement from the following options for closed loop stability of the system.
