What we have done the last few weeks:
26.09.2011: PID tuning (plantwide6_tuning)
03.10.2011: Stabilizing layer (plantwide4_regulatory+distillation)
10.10.2011: Advanced/supervisory control. MPC (plantwide5, plantwide5b)

Plans:

11.10.2011: 1300: Krister Forsman, Perstorp (with pizza)
11.10.2011: 14-16: Mehdi Panahi on MPC using Unisim (exercise 6)

17.10.2011: No lecture, deadline exercise 6
24.10.2011: Decentralized control lecture (plantwide7), final lecture.

19 Sep. 2011

Today we went through the remaining part of plantwide2-cv1-selection (active constraints)
+ we went through plantwide3-tpm-location (see the Aske paper for more details).

You can now start Exercise 3 on consistency of inventory control.
The deadline is Monday 26 September (I hope this is OK because we got a bit delayed with Exercise 2).

The solution for Exercise 1 (Problems 1 and 2) is now available.

This week: Please do exercise 1, part 2 (it has been updated). Deadline: Monday 12 Sep)

Next week (Monday 12 Sep. 13-15): Introduction to use of Unisim/Hysys by Mehdi (Exercise 2)

We had the second lecture today (Monday 13-16).
I covered up to slide 60 in plantwide2-cv1-selection-soc.ppt (that is, everything except active constraints + some case studies).
I also derived the "exact local method" on the board. For details see:
plantwide2-exact-local-method_lecture-notes.pdf

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 (important 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 combination: 1. Nullspace method HF=0 , 2. Exact local method

22 Aug. 2011

We had the first lecture today. I covered up to slide 35 in plantwide1-intro+optimal-operation.ppt (up to the HDA example).
We will continue the lectures on 05 or 06 September.

In the meantime:

1. Start reading the three papers that begin with plantwide (from 2000, 2004 and 2011)

2. Do Exercise 1 (but on Problem 2 you only need to do
part 2-1 now). Please send the solution to Mehdi by Thursday 01 September.
For questions/help for the exercises, ask Johannes (for Problem 1) and Mehdi (for Problem 2).

16 Aug. 2011

The first lecture and information meeting will be

Monday 22 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.

You can start with Exercise 1 NOW (Problem 1). It gives you a good introduction!
Questions: Mehdi Panahi (sits in K4-212

Note: The initial lectures are combined for the "emnemodul" TKP8 and the "PhD course" KP8115.
Do not hesitate to ask or send emails!
Welcome to the course!

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.
