Discrete LQ optimal control with integral action: A simple controller on incremental form for MIMO systems.
(Journal article; Peer reviewed, 2012)A simple Linear Quadratic (LQ) optimal controller of velocity (incremental) form with approximately the same properties as a conventional PID controller of velocity form is presented, i.e. integral action. The proposed ... -
Model-free optimal anti-slug control of a well-pipeline-riser in the K-Spice/LedaFlow simulator
(Journal article; Peer reviewed, 2015)Simplified models are developed for a 3-phase well-pipeline-riser and tested together with a high fidelity dynamic model built in K-Spice and LedaFlow. These models are developed from a subspace algorithm, i.e. Deterministic ... -
Relaxed Ziegler-Nichols closed loop tuning of PI controllers
(Journal article; Peer reviewed, 2013)A modification of the PI setting of the Ziegler-Nichols closed loop tuningmethod is proposed. The modification is based on a combination of the Skogestad SIMCtuning formulas for ´´integrator plus time-delay´´ processes ... -
The Good Gain method for simple experimental tuning of PI controllers
(Journal article; Peer reviewed, 2012)A novel experimental method { here denoted the Good Gain method { for tuning PI controllers is proposed. The method can be regarded as an alternative to the famous Ziegler-Nichols' Ultimate Gain method. The approach taken ...
