Determine the transfer functions for $\frac{C_3}{Q_1}$ and $\frac{C_3}{Q_2}.$

Assume the process is controlled with a proportional controller. Create a block diagram for

the process. Identify all the transfer functions.

If the gain of proportional controller is $100,$ plot the output of the controller for a unit$-$step

change in load and set point, using simulink. Report the offset in each case.

Make a first order Pade approximation $(1/1)$ for the time delay, use Routh stability criteria

to determine the stability limits for $K_c.$

Use Simulink to identify $K_{cu}$ and $P_u$ by hit$-$and$-$trial.

Use ZN settings for the proportional$-$integral controller and plot using Simulink the output

for a unit step set point change.
