investigate the range of the
gain K that would guarantee the stability of the system and hence,
find the
frequency of oscillation at the marginal stability point.

(e) An input r(t) = 1.1u(t) is applied to the system, where the
function u(t) is the unit
step function. It is desired that the steady-state error, ess <
0.12. Determine the
minimum value of K that would satisfy the design requirement.
