Adaptive Linear Grey-Box Models for Model Predictive Controller of Residential Buildings
Yu, Xingji; Georges, Laurent; Imsland, Lars Struen (Peer reviewed; Journal article, 2022)Model predictive control (MPC) is an advanced optimal control technique to minimize a control objective while satisfying a set of constraints and is well suited to activate the building energy flexibility. The MPC controller ... -
Data pre-processing and optimization techniques for stochastic and deterministic low-order grey-box models of residential buildings
Yu, Xingji; Georges, Laurent; Imsland, Lars Struen (Journal article; Peer reviewed, 2021)Grey-box models are data-driven models where the structure is defined by the physics while the parameters are calibrated using data. Low-order grey-box models of the building envelope are typically used for two main ... -
Data-driven simultaneous identification of the 6DOF dynamic model and wave load for a ship in waves
Ren, Zhengru; Han, Xu; Yu, Xingji; Skjetne, Roger; Leira, Bernt Johan; Sævik, Svein; Zhu, Man (Peer reviewed; Journal article, 2023)In marine operations, the performance of model-based automatic control design and decision support systems highly relies on the accuracy of the representative mathematical models. Model fidelity can be crucial for safe ... -
Influence of thermal zoning and electric radiator control on the energy flexibility potential of Norwegian detached houses
Johnsen, Thea; Taksdal, Katrine; Clauß, John; Yu, Xingji; Georges, Laurent (Journal article; Peer reviewed, 2019)Energy flexibility of buildings can be used to reduce energy use and costs, peak power, CO2eq- emissions or to increase self-consumption of on-site electricity generation. Thermal mass activation proved to have a large ... -
Investigation of the Model Structure for Low-Order Grey-Box Modelling of Residential Buildings
Yu, Xingji; Georges, Laurent; Knudsen, Michael; Sartori, Igor; Imsland, Lars Struen (Chapter, 2019)Model Predictive Control (MPC) is a key technology to activate the building energy flexibility. A reliable control-based model should be developed for each specific building. The structure of grey-box models is usually ...
