The distillation column in Fig. 15.8 has the following I)
Chapter 15, Problem 15.10(choose chapter or problem)
The distillation column in Fig. 15.8 has the following transfer function model:
\(\frac{Y^{\prime}(s)}{D^{\prime}(s)}=\frac{2e^{-20s}}{95s+1}\quad\ \ \ \ \frac{Y^{\prime}(s)}{F^{\prime}(s)}=\frac{0.5e^{-30s}}{60s+1}\)
(a) Design a feedforward controller based on a steady-state analysis.
(b) Design a feedforward controller based on a dynamic analysis.
(c) Design a PI feedback controller based on the Direct Synthesis approach of Chapter 12 with \(\tau_{c}=30\).
(d) Simulate the closed-loop response to a unit step change in the disturbance variable using feedforward control only and the controllers of parts (a) and (b). Does the dynamic controller of part (b) provide a significant improvement?
(e) Repeat part (d) for the feedforward-feedback control scheme of Fig. 15.11 and the controllers of parts (a) and (c), as well as (b) and (c).
(f) Which control configuration provides the best control?
