Problem 6.52PP
The open-loop transfer function of a unity-feedback system is
C (J) =■ j (H-5/5K1+»/20)*
(a) Sketch the system block diagram, including input reference commands and sensor noise.
(b) Use Bode plot sketches to design a compensator for G(s) so that the closed-loop system 
satisfies the following specifications;
(i) The steady-state error to a unit-ramp input is less than 0.01.
(ii) PM >45“.
(iii) The steady-state error for sinusoidal inputs with a)
