    • Slug handling with a virtual harp based on nonlinear predictive control for a gravity separator 

      Backi, Christoph Josef; Krishnamoorthy, Dinesh; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)
      This paper presents a nonlinear model predictive control approach for a three-phase gravity separator model. The aim of the controller is to dampen slug-induced, oscillatory disturbances in the inflow to the gravity ...
    • Steady-State Real-time Optimization using Transient Measurements 

      Krishnamoorthy, Dinesh; Foss, Bjarne Anton; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)
      Real-time optimization (RTO) is an established technology, where the process economics are optimized using rigourous steady-state models. However, a fundamental limiting factor of current static RTO implementation is the ...
    • Systematic design of active constraint switching using se-lectors. 

      Krishnamoorthy, Dinesh; Skogestad, Sigurd (Peer reviewed; Journal article, 2020)
      Selector logic is a simple and effective tool to switch between different controlled variables associated with change in active constraints. Selector blocks have been extensively used in the process control industry for ...
