Question:

Implement Alternatives 3 and 4 using the Simulink model. This will require tuning a cascade loop to control composition in each case.
(a) Evaluate the response of these controlled plants for a step change in F0 without using the ratio controller proposed by Wu and Yu.
(b) Repeat (a) with a controller used to ratio the column feed flow rate to the reactor feed flow rate. How do the responses in (a) and (b) compare?
