  4. NTNU, Trondheim • Process Control professors: • Bjarne Foss • Morten Hovd • Jens Balchen • Heinz Preisig • Sigurd Skogestad EE ChE

  5. Sigurd Skogestad • Born in 1955 • 1978: Siv.ing. Degree (MS) in Chemical Engineering from NTNU (NTH) • 1980-83: Process modeling group at the Norsk Hydro Research Center in Porsgrunn • 1983-87: Ph.D. student in Chemical Engineering at Caltech, Pasadena, USA. Thesis on “Robust distillation control”. Supervisor: Manfred Morari • 1987 - : Professor in Chemical Engineering at NTNU • Since 1994: Head of process systems engineering center in Trondheim (PROST) • Since 1999: Head of Department of Chemical Engineering • 1996, 2005: Book “Multivariable feedback control” (Wiley) • 2000, 2003: Book “Prosessteknikk” (Tapir) • Group of about 10 Ph.D. students in the process control area

  6. Research: Develop simple yet rigorous methods to solve problems of engineering significance. • Use of feedback as a tool to • reduce uncertainty (including robust control), • change the system dynamics (including stabilization; anti-slug control), • generally make the system more well-behaved (including self-optimizing control). • limitations on performance in linear systems (“controllability”), • control structure design and plantwide control, • interactions between process design and control, • distillation column design, control and dynamics. • Natural gas processes
