a) Find the range of gain, K. for the system below will cause the system to be stable, unstable, and marginally stable. Assume K>0 R(s) E(s) K s(s+ 7)(8 +11) C(s) b) Determine the steady-state error for 1) r(t) = u(t) where u(t) is a unit step function and 2) r(t) = tu(t) a ramp input c) Determine the steady-state error for r(t) = tu(t). If you add Pl controller to the above system - d) Find the steady state value when the input is a unit step function r(t) = u(t) a
