  1. 1. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings

    Författare :Mohsen Soleimani-Mohseni; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building models; state space models; feedback; thermostats; transfer function models; intelligent buildings; ON-OFF controllers; Feed-forward; PIL controllers;

    Sammanfattning : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. LÄS MER
