PI controller tuning based on historical data
(Master thesis, 2013)The effects on PI controller tuning related to information quality in input-output datahave been investigated. This is relevant as many industrial control systems store thiskind of data and it is desirable to be able to ... -
Pilot study of Early Meal Onset Detection from Abdominal Sounds
(Chapter, 2019)A typical artificial pancreas depends only on the continuous glucose monitoring (CGM) value for insulin dosing. However, both the insulin infusion and the glucose sensing are subject to time delays and slow dynamics. An ... -
Pipeline Liquid Control using Nonlinear MPC and OLGA: Optimal Utilization of Available Liquid Buffer Volume during Pipeline Transients
(Master thesis, 2007)Pipelines with multiphase flow will exhibit large and highly nonlinear liquid rates during transients caused by changes in production rate. This requires either a large separator (slug catcher) downstream, capable of ... -
Placement of virtual inertia from HVDC terminals based on a frequency deviation index
(Chapter, 2021)This paper presents an approach for assessing the most suitable locations to provide virtual inertia by HVDC converters. A frequency deviation index quantifying the maximum distance in Hz from each bus in the power system ... -
