Block diagram model of a position control system is shown in Fig. P2.3:

(a) In absence of derivative feedback ( \(\left.K_{t}=0ight)\), determine damping ratio of the system for amplifier gain \(\mathrm{K}_{\mathrm{A}}=5\). Also find the steady state error to unit ramp input.
(b) Find suitable values of the parameters \(\mathrm{K}_{\mathrm{A}}\) and \(\mathrm{K}_{t}\) so that damping ratio of the system is increased to 0.7 without affecting the steady state error as obtained in part (a).
