For the linear, time-invariant system whose block diagram is shown in Fig.
with input x(t) and output y(t),
(a) Find the transfer function.
(b) For the step response of the system [i.e. find y(t) when x(t) is a unit step function and the initial conditions are zero]
(c) Find y(t), if x(t) is as shown in Fig. and the initial conditions are zero.

Block diagram model of a position control system is shown in figure.
(a) In absence of derivative feedback (Kt=0) , determine damping ratio of the system for amplifier gain KA=5. Also find the steady state error to unit ramp input.
(b) Find suitable values of the parameters KA and Kt so that damping ratio of the system is increased to 0.7 without affecting the steady state error as obtained in part (a).
