A unity feedback system has a forward path transfer function 2000 S(S4) (S + 8) (S + 10) G(s) 1) If a unity ramp is applied the steady state error is? II) Find the step error constant of a unity feedback system whose forward transfer 1 function G(s) = (S+2)(S+3) III) Consider a system with the transfer function G(s): The damping ratio will 0.5 when K is? = S+6 KS + S +6
