PROST

• Process-systemteknikk

• Process systems engineering Trondheim

• Appointed in 1994 as a “Strong Point Center at NTNU and SINTEF”– 5 years with 1 million NOK in annual suppurt from NTNU and SINTEF

– Originally: Cooperation between process systems groups at Chemical Engineering (Skogestad, Hertzberg, Lien) and Engineering Cybernetics (Foss) + associated SINTEF groups

– Later extended to mechanical engineering (Asbjørnsen, Gundersen)

• One of the largest process systems groups in Europe. 40-50 people.– Industry seminars, internal seminars

– Ph.D. and postdoc support

– Internal email newsletters (mostly from Sigurd)

PROST's main research areas are:

• Process modelling

• Process simulation and optimization, both static and dynamic

• Process control

• Process synthesis

• Process operations

Research: Develop simple yet rigorous methods to solve problems of

engineering significance.

• Use of feedback as a tool to1. reduce uncertainty (including robust control),

2. change the system dynamics (including stabilization),

3. generally make the system more well-behaved (including self-optimizing control).

• limitations on performance in linear systems,

• control structure design and plantwide control,

• interactions between process design and control,

• distillation column design, control and dynamics.

• Natural gas processes

13

Optimal operation in practice:

• "The goal is to find a self-optimizing control structure where acceptable operation under all conditions is achieved with constant setpoints for the controlled variables."

14

Self-optimizing Control – Illustrating Example

• Optimal operation of Marathon runner, J=T– Any self-optimizing variable c (to control at constant

setpoint)?• c1 = distance to leader of race

• c2 = speed

• c3 = heart rate

• c4 = level of lactate in muscles

15

Group work

• Main objective: Suggest collaborative research project(s) for the “new” Ph.D. students in your group. Should be possible to include in Ph.D. thesis.

• Topic should be such that a paper can be finished within 5 months (Feb. 2003)

• For each project make a transparency with:Title: ……………………..

Suggest names or desired background (at least two people from different groups) (e.g., Elvira Aske + one from Bolland’s group)

Short abstract:………..

• Extra task (one transparency each):Ideas for seminars, social events, etc. for the Natural Gas Systems Group
