• #### Model based control for run-of-river system. Part 1: Model implementation and tuning ﻿

(Journal article; Peer reviewed, 2015)
Optimal operation and control of a run-of-river hydro power plant depends on good knowledge of the elements of the plant in the form of models. River reaches are often considered shallow channels with free surfaces. A ...
• #### Model based control for run-of-river system. Part 2: Comparison of control structures ﻿

(Journal article; Peer reviewed, 2015)
Optimal operation and control of a run-of-river hydro power plant depend on good knowledge of the elements of the plant in the form of models. Both the control architecture of the system, i.e. the choice of inputs and ...
• #### Model based flow measurement using venturi umes for return flow during drilling ﻿

(Journal article; Peer reviewed, 2017)
In an oil well drilling operation, a proper knowledge of the return fluid flowrate is necessary both for the stabilization of the bottom hole pressure of the well and also as a primary indication of a kick or loss. In ...
• #### Model Predictive Control with Integral Action: A simple MPC algorithm ﻿

(Journal article; Peer reviewed, 2013)
A simple Model Predictive Control (MPC) algorithm of velocity (incremental) form is presented. The proposed MPC controller is insensitive to slowly varying system and measurement trends and therefore has integral action. ...
