• Global optimization of multiphase flow networks using spline surrogate models 

      Grimstad, Bjarne André; Foss, Bjarne Anton; Heddle, Richard; Woodman, Malcolm (Journal article; Peer reviewed, 2016)
      A general modelling framework for optimization of multiphase flow networks with discrete decision variables is presented. The framework is expressed with the graph and special attention is given to the convexity properties ...
    • Petroleum production optimization - A static or dynamic problem? 

      Foss, Bjarne Anton; Knudsen, Brage Rugstad; Grimstad, Bjarne André (Journal article; Peer reviewed, 2018)
      This paper considers the upstream oil and gas domain, or more precisely the daily production optimization problem in which production engineers aim to utilize the production systems as efficiently as possible by for instance ...
    • Studies in Output Feedback Control 

      Grimstad, Bjarne André (Master thesis, 2009)
      This master s thesis studies the recently proposed initialization scheme for the H2-optimal static output feedback problem [1]. The initialization scheme consists of solving a convex quadratic programming (QP) problem to ...
