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 pan of this work is an 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 ofthe 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 Furzy 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 rcsults of different contmllers are presented and discussed.

Angeregt durch Untersuchungen des dynamischen Verhaltens von Windversorgungssystemen für Hochöfen und verfahrenstechnische Anlagen, wird ein dynamisches Modell für die in solchen Anlagen den Verdichtern direkt nachgelagerten Exzenter-Rückschlagklappen entwickelt. Das resultierende Modell besteht aus einer nicht linear en, gewöhnlichen Differentialgleichung zweiter Ordnung. Einige exemplarische Simulationsergebnisse veranschaulichen das nichtlineare asymmetrische Verhalten der Klappen. Stimulated by investigations of the dynamical behavior of blast supply systems for blast furnaces and chemical plants, a dynamical model is developed for the excenter check-valvesimmediately after the compressor. The resulting model consists of a nonlinear ordinary differential equation of order two. Several exemplary simulation results clearly demonstrate the nonlinear asymmetric behavior of the check-valves.
