Linear Control Systems, Do not post a Matlab solution please, I need this worked out.
Show transcribed image text (2) Given the control system- G(s) = K, G(s)= 1/s(s + 4)(s + 5) (a) Assuming that the system is stable, find the steady-state error if the input to the system is a unit step. (b) Find the range of gain K for which the result of (a) applies. (c) Determine the value of K (K not equal to 0) that will result in the system being marginally stable. (d) Find the frequency of oscillation of the system output in response to a unit step input when the system is marginally stable. (e) Find the location of all the roots of the system characteristic equation for that value of K found in (c).
