- 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.
