Question: Consider the stirred-tank heating system shown in Fig. E. It is desired to control temperature T2 by adjusting the heating rate Q1 (Btu/h) via voltage

Consider the stirred-tank heating system shown in Fig. E. It is desired to control temperature T2 by adjusting the heating rate Q1 (Btu/h) via voltage signal V1 to the SCR. It has been suggested that measurements of T1 and To, as well as T2, could provide improved control of T2.

(a) Briefly describe how such a control system might operate and sketch a schematic diagram. State any assumptions that you make.

(b) Indicate how you would classify your control scheme, for example, feedback, cascade, or feedforward. Briefly justify your answer.
