Abstract:

The present master thesis was conducted in collaboration with the company Fr. Sauter AG. The goal of this thesis was to investigate different modelling and control techniques on a one-floor, threerooms building located in Basel. In the first step a physical model was derived using the BRCM Toolbox, which was developed at ETH. In the second step, experiments were performed on the building and models were derived, using common system identification techniques. The investigated input signals were the step up/down and the PRBS signal. Moreover, a relay feedback with lead/lag controller approach was also investigated. Using additional validation data, the performances of the different models were compared. All models showed a reasonable performance, except one of the PRBS models, due to a missing pole at lower frequencies. The step up/down and the Toolbox models were then used within two different MPC formulations. The control techniques investigated in this project were a standard and an offset-free MPC formulations. The implemented controllers were tested on the real building and the results were compared with an existing P-controller.
