(b) Figure 04(b) illustrates a diagram of continuous stirred tank reactor system. The objective of the system is to maintain the temperature of the reaction mass at the desired value when subjected to changes in inlet concentration (Ca) and temperature (T.). In Figure Q4(e), the left part of the figure shows the conventional feedback control scheme, while the right part is a cascaded feedback control scheme of the reactor system. 1) Draw the block diagram representation of a cascade control loop. (6 marks) (ii) Explain TWO (2) distinct features of the cascaded control scheme, in comparison with the conventional feedback based on the Figure 04(e). (4 marks) (ii) In Figure Q4(c), explain how the cascade control can be used to improve the response of a single feedback strategy.
