"An integrated control system for optimising the energy consumption and user comfort in buildings";
in: "IEEE International Conference on Control Applications", issued by: IEEE; IEEE, Glasgow, Scotland, 2002, 127 - 132.

In this paper a HVAC system consisting of the thermal and ventilation subsystem and the lighting
subsystem is analyzed in detail. The objective of this work is the development of an integrated control
system, whose aim is to optimize the energy consumption and the user comfort. The focus of the first
part of this work is on the analysis of the different subsystems. The entire control system is described
in detail. The cross coupling, which links the thermal system with the lighting system, is specified.
This allows a separation of the control algorithms according to the requirements.
The core objective of this paper is the design of several intelligent thermal control algorithms. An algorithm
using a Fuzzy controller and an adapting power profile, a controller which uses the same algorithm
as mentioned before but which optimizes the Fuzzy controller parameters using Genetic Algorithms
and a generalized predictive controller (GPC) are presented. Different aspects of the control
strategies, the diverse specifications of the algorithms and any restrictions concerning the implementation
are listed. Last but not least simulation results of different controllers are presented and
discussed.
