Describe the
motivation for control with 2 examples
 1 CSTR polymerization
 1.1 Diagram first.
 1.2 Chemistry
 1.3 Basic Control Strategies
 1.4 Recipie Based Operation
 2. Distillation Column
 2.1 Diagram
 2.2 Basic Theory and what is optimized?

Strategy for
process control
Discuss Constraint issue in general and result of tight process control with respect to constraints.

Automation
Hierarchy Layer
 Draw the basic automation hierarchy layer.
 Describe in 12 lines each level.

Feed Forward and
Feed Backward controller
 1. Draw and explain both with an example.
 2. Basic Usage,facts and consequences for feed backward controller.

PID
Controller(math,laplace,real PID)
 IDEAL  Time series and laplace form.
 REAL  PID
 PID with Dpart only for the process variable.

Why PID is used so
much?
 5 important points.
 simplicity
 tuning
 one solution to multiple problems
 linearity issues
 based on system response

Effect of control
parameters on step response and PID tuning
K_{P}, T_{N}, T_{V} varied either too large or too small.

PID tuning methods
at least 5
 Ziegler and Nichols
 Chien, Hrones and Reswick
 Time summation Constant
 Optimum Absolute Value
 Bode Diagram
 Root Locus curves

Usability of PID
from practical prespective
6 points

4 Distillation
profiles for a binary mixture

Schematc View on
column operation.
 Describe the diagram
 steam consumption Y axis
 Feed Flow X axis
 efficient zone, comfort zone and optimal curve.and doing what produces an efficient column.

Column Control.
Measured variables? Manipulated Variables? Problem from control point of
view.

Problems with
traditional purity measurements


Distillaation
heuristic rules  7 in all
 1. Mass balance
 2. Level control
 3. T control
 4. Dynamics
 5. Decoupling
 6. Fixed flow rate caution
 7. Fluid Dynamics

1.Distillation Column
Control Concept application(no quality measurements). Do it on the printed diagrams.
2. Where exactly should the controller and sensor be placed and for what kind of feed??
3. When there is no profile what should be done?

Distillation Column
pressure Control Concepts.Do it on the printed diagrams.
explain also the strategy and alternatives.
