An Comparative Study: Model-Based vs. Noise Estimation Approach for State Estimation
Abubakar Bampoye (Master thesis, 2023)Denne oppgaven tar for seg en analyse av en bioprosessmodell, som omfatter en sammenlignende undersøkelse av to forskjellige estimeringsteknikker. Selve estimeringsteknikkene er foreslått av Krog & Jäschke[21] og Berry & ... -
Optimization of a Reactor Network for Production of Butyl Butyrate by an Attainable Region Analysis
Krog, Halvor Aarnes (Master thesis, 2017)Butyl butyrate is a promising supplement for jet fuel and diesel. It can be produced in a biotechnological process, by an esterification reaction between butanol and butyric acid. These intermediates can in turn be produced ... -
Simple and Robust Formulations of the Unscented Kalman Filter and Model Predictive Control
Krog, Halvor Aarnes (Doctoral theses at NTNU;2024:93, Doctoral thesis, 2024)This thesis focuses mainly on state estimation by the Unscented Kalman filter (UKF), and partly on robust nonlinear model predictive control (RNMPC). Our aim is to refine or develop algorithms which are simple to implement, ... -
The Simple Solution for Nonlinear State Estimation of Ill-Conditioned Systems: The Normalized Unscented Kalman Filter
Krog, Halvor Aarnes; Jäschke, Johannes (Journal article; Peer reviewed, 2023)An easy-to-implement method for nonlinear state estimation for ill-conditioned systems is proposed. By propagating standard deviations and correlations instead of the covariance in the unscented Kalman filter (UKF), the ...
