Active Compressor Surge Control System Using Piston Actuation Theory, Design, and Experiments
Uddin, Nur (Doctoral thesis at NTNU;2016:80, Doctoral thesis, 2016)This thesis presents a novel active compressor surge control system using piston actuation, and this system is called the piston-actuated active surge control system (PAASCS). This work addresses the development of PAASCS ... -
Combining building automation control systems with envelope retrofitting to improve the energy performance of cold climate housing
Felius, Laurina Cornelia (Doctoral theses at NTNU;2021:167, Doctoral thesis, 2021)Improving the energy efficiency of buildings by combining envelope and energy systems retrofitting with smart technologies is recommended by the Energy Performance of Buildings Directive. The largest share of the existing ... -
Design av trefase vekselretter og motorkontroller til synkronmotor
Tran, Emanuela; Meisal, Oscar Øgar; Bergsvik, Simen (Bachelor thesis, 2021)Oppgaven dokumenterer utviklingen av en vekselretter-prototype og motorkontroller for en børsteløs DC-motor.

Direct training of robots using a positional deviation sensor
Dessen, Fredrik (Doktor ingeniøravhandling;1988:33, Doctoral thesis, 1988)A device and system for physically guiding a manipulator through its task is described. The device consists of inductive, contact-free positional deviation sensors, enabling the rcbot to track a motion marker. Factors ... -
Optimal Comfort with Limited Power
Rødal, Mads Dyrlid (Master thesis, 2018)Electricity consumption is growing and with more efficient equipment introducing larger power peaks. Reducing the power peaks can substantially reduce the electricity expenses for a building. In 2015 it was presented that ... -
Optimizing Order to Minimize Low-Pass Filter Lag
Dessen, Fredrik (Journal article; Peer reviewed, 2018)This paper develops a tool kit for designing low-pass filters to exhibit the smallest possible phase drop. Based solely on the stopband requirements, it is thus possible to find the best order for a filter to be employed ... -
Process Data Mining for Parameter Estimation: With the DYNIA Method
Fordal, Arnt Ove (Master thesis, 2010)Updating the model parameters of the control system of an oil and gas production system for the reasons of cost-effectiveness and production optimization, requires a data set of input and output values for the system ... -
Upgrading the Smartness of Retrofitting Packages Towards Energy-Efficient Residential Buildings in Cold Climate Countries: Two Case Studies
Felius, Laurina C; Hamdy, Mohamed; Dessen, Fredrik; Hrynyszyn, Bozena Dorota (Peer reviewed; Journal article, 2020)Improving the energy efficiency of existing buildings by implementing building automation control strategies (BACS) besides building envelope and energy system retrofitting has been recommended by the Energy Performance ... -
Wood burning habits and its effect on the electrical energy demand of a retrofitted Norwegian detached house
Felius, Laurina C; Thalfeldt, Martin; Georges, Laurent; Hrynyszyn, Bozena Dorota; Dessen, Fredrik; Hassan Mohamed, Mohamed Hamdy (Journal article; Peer reviewed, 2019)Using firewood as a space heating source is a popular solution in Norwegian housing and can significantly reduce the electrical energy demand of houses. This study analysed habits and reasons for using a wood stove from ...
