**Unformatted text preview: **(a) Show that can be approximated by an FOPTD model and determine what that model is equal to. (b) Use the Routh stability methods for your FOPTD model to find the range of Kc values that will yield a stable closed-loop system. (c) Determine the Kcm using the direct substitution method. Question 5 For the standard feedback control loop you have: Determine whether the value of a affects the stability of the closed-loop system. Assume Kc>0. You do not need to solve for the roots of the characteristic equation to answer the question. Question 6 The set-point of the control system under proportional control (Kc=2.0) undergoes a step change of magnitude 2. For (a) Determine when the maximum value of y occurs. (b) Determine the offset. (c) Draw a sketch of y(t) as a function of time. (d) If this is a standard feedback control loop, determine the range of values of Kc for which the loop will be stable using Routh array....
