18 Sep. 2013 (2 hours +)
- Repeated exact local method, which will be used on exercise 4
- Went through rest of plantwide1-slides, with emphasis on active constraint regions
- 1530-1700: Vlad on exercise 3 (recycle process)

11 Sep. 2013 (2 hours+):
- Covered exact local method
- Exercise 2 
----

04 Sep. 2013 (3 hours)
Topics covered today:
   (see also file lecture-cv-selection.docx)
Goal: Optimal economuc operation: min_u J(u,d)
Implement by selecting "self-optimizing" Cv=c = Hy
1. Rules
 - control active constraints
 - Purity constraint on expensive product is always active
 - ideal unconstrained c=Ju
 - do NOT select c = J (cost function or anything which reaches min or max)
    Example: Reactor-recycle process where one fixes V (c=V).

2. Simple rules for c:
(i) Want Fc  = HF small (-> small disturbance sensitivity)
(ii) Want c to be easy to measure and control  -> not composition
(iii)Want G = HGy large (-> small noise sensitivity)


3. Nullspace method

News: 27 Aug. 2013

Yesterday (Monday) I went through the first plantwide control slides, up to the part about steady-state degrees of freedom.

Tomorrow (Wednesday) at 12 we will have an exercise session (Exercise 1) with Vlad. Please meet prepared!

-News: 07 Aug. 2013

The first lecture and information meeting will be 

    Monday 26 August at 1015-1200 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/

You can start with Exercise 1 NOW (Problem 1). It gives you a good introduction!
Questions:  Vlad Minasidis (vladimiros.minasidis@ntnu.no) (sits in K4-207)

You can also start reading the Chapter on "Economic plantwide control" from the book by Rangaiah and Kariwala (Editors) on Plantwide control. Recent Developments and Applications, Wiley, 2012:

       papers-pensum/plantwide-bookchapter-11.pdf

If you have time, you may also start reading the three other papers that start with plantwide.. 
They are quite similar, but there are some differences and this is why i have included all four!

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.
