0. Summary of last activities:
06 Sep. Lectures part 3 covered rest of uke2_plantwide (on selection of c=Hy)
09 Sep. Use of Unisim (by Mehdi)
16 Sep. Lectures part 4 covered uke3_plantwide (on location of TPM and consistency)

1. There will be no lecture on Monday 20 Sep. 
Next lecture: Monday 27 Sep. 8-10.
The topic will be PID tuning (see slides part2_tuning).

2. Exercise 4 on consistency is now available. Deadline is Friday 24 September.
Note that Kida has promised a prize for the best solution to the last problem (no.24; but don't worry there are not 24 problems, the numbering is just a bit strange).

Lectures part 2:
Today we discussed optimal operation + choice of controlled variables (CVs = c).
Slides: Finished uke1_plantwide + half of uke2_plantwide

Summary of main topic:
Let y be the available measurements, including the inputs (MVs).  The CVs are 

   c = H y 

and the issue is to find the non-square matrix H.
H could be a selection matrix (if we control individual y's) or a combination matrix. 

What should c=Hy be?
  1. Control active constraints (inportant to reduce back-off for these)
  2. Control "self-optimnizing" variables with small loss when there are disturbances.
	- maximum gain rule (maximize gain from u to c)
        - optimal conbination: HF=0 (nullspace method)

We had the first lectures today: Intro + started on degrees of freedom (uke1_plantwide)
Future lectures: Mondays 8-10.

You can start with Exercise 1 NOW (Problem 1). It gives you a good introduction!

The first lecture and information meeting will be 

Monday 23 August at 1315-1500 in room K4-205.

There will be an introduction and we will discuss time and place for the rest of the term. 

More information: http://www.nt.ntnu.no/users/skoge/vgprosessregulering/

Note: The initial lectures are combined for the "emnemodul" TKP8 and the "PhD course" KP8115.

Course overview:
PLANTWIDE PROCESS CONTROL

This is a module (half a normal course) offered to the 5th year students at NTNU. 
It is taught every autumn, starting in late August.

Topics:
1. Optimal operation (economics) and degrees of freedom
2. What should we control from an economic point of view? (including self-optimizing control)
3. Inventory control, including location of throughput manipulator
4. Base layer control (regulatory layer; stabilizing control)
5. Tuning of PID controllers
6. Multivariable control: Interactions, decentralized control, practical use of MPC


---------------------------------------------------------------------------

BASIC INFO:

The lectures form the basis for two courses:

1. TKP10  Process Control, Advanced Course. Master specialization module  (3.75 EDU; must be taken together with another 3.75 EDU module to get full course)

2. KP8115 Advanced process control. PhD course (7.5 ECU)

2. Ph.D. course KP 8115 - Advanced process control (7.5 ECU)
Lecturer: Sigurd Skogestad 

The Ph.D. course and the 5th year Master specilization ("emnemodul") have
an initial common part, but the Ph.D. course has additional topics and
a larger emphasis on theory.
