For the shown system. find the closed loop steady-state error for the inputs r(t) = 2 and r(t) = 4t. For the shown system and for the value of A causing marginal stability, find out the marginally stable poles of the system. Given: G(3) response. 1 (5-0.5) + r(t) r(t) 5/(s+4s+45) K/s(s'+4 s'+45+2) v(t) v(t) For this given system. find out the OS (overshoot) of its closed-loop step
