Question: The E 1 0 . 1 5 unit feedback system has the following transfer function: G ( s ) = 1 0 0 / s

The E10.15 unit feedback system has the following transfer function: G(s)=100/s(s+8). The steady-state error for gradient input r(t)= At is less than 0.16 A, and we want to obtain a phase margin of 35deg and an intersection frequency of 20 rad/s. Determine whether the ground compensator or the ground compensator is necessary.
