Extracted text: Internal model control (IMC) is a control method that can be applied in many different situations with potentially different control objectives. As a result, IMC could be represented in different block diagrams. a) Consider the feedback control scheme of Figure 3.1, where GM is the model of the real process Gp. For now assume this model is perfect. Determine the ideal controller G, which allows a perfect set-point tracking; or if this is not possible explain why not. Ysp (s) E(s) Uc(s) Y(s) Gc(s) Gp(s) Ym(s)+ GM(s) Figure 3.1 b) Briefly discuss three potential shortcomings of the control scheme in Figure 3.1 with the ideal controller designed in Question 3a).
