Process Control Group

Part of: PROST at Chemical Engineering

Head: Sigurd Skogestad

The process control group presently consists of 2 Professors, 1 post.doc. and 10 Ph.D. students. In addition, we are part of the 40-member Strong Point Center in Process Systems Engineering in Trondheim (PROST). PROST consists of people from Chemical Engineering, Electrical Engineering and Mechanical Engineering (both at NTNU and SINTEF) and is the second largest process systems engineering center in Europe (after Imperial College).

The activity of the process control group focuses on developing tools which are rigorous, yet useful in practice. The aim is to provide the engineer with tools to assist in problem solving. Main research areas:

• Plantwide control and optimization (including self-optimizing control)
• Feedback as a tool to reduce the effect of uncertainty (including robust control)
• Controllability of processes (achievable control performance)
• Control structure design (including decentralized control)
• Model-based control system design
• Design and control of distillation processes (continuous and batch)
• Stabilization of chemical processes and fluid flow

To find out more about our activity, look at our check out the Ph.D. Theses and Publications available on the web (as postscript or pdf files).

Our activity has been strengthened by the addition of Professor Heinz Preisig (previously TU Eindhoven) who joined our Department in January 2003.
