  1. 1. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonas Cederberg; [2023]
    Nyckelord :Lumped Parameter Thermal Network; Resistance-Capacitance model; Parameter estimation; Modelling of Dynamical Systems; Thermal modelling; Temperature Prediction; Termiskt nätverk med klumpade parametrar; Mostånds-kapacitans modell; Parameterestimering; Modellering av dynamiska system; Termisk modellering; Temperaturprediktion.;

    Sammanfattning : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

  2. 2. Electrohydraulic Power Steering Simulation : Dynamic, thermal and hydraulic modelling

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oskar Svensson; [2019]
    Nyckelord :PMSM; SVPWM; vector control; FOC; lumped parameter model; LPM; hydraulic pump; simulation;

    Sammanfattning : There are several benets of electrohydraulic power steering systems, as compared to hydraulicpower steering systems where the pump is driven directly by the engine of the vehicle. Someof these benets are increased eciency and improved steering performance. LÄS MER

  3. 3. Thermal modelling of an FZG test gearbox

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Carlos Prakash del Valle; [2014]
    Nyckelord :Thermal network; FZG gear test rig; heat flow; temperature; MATLAB; ODE; Termiskt nätverk; FZG kugghjuls-rigg; värmeflöde; temperatur; MATLAB; ODE;

    Sammanfattning : Gearboxes are always subject of study in order to increase their efficiency. Energy losses in gear contacts are transformed into heat which is distributed among the gearbox components increasing their temperature. LÄS MER
