Abstract-Modern intelligent control systems for building automation, ambient living or surveillance control have to deal with upcoming requirements like increasing complexity of sensor data, or supporting human beings at their jobs. Therefore the system has to decide on actions taken in case of unforeseen situations. The most complex as well as effective decision making unit that is known, is represented by the human mind. Therefore it seems to be feasible to emulate the human mind in order to design a system for approximating its abilities. While in current Artificial Intelligence a number of generally accepted models, which rely on psychological or neurological theory, are known this paper will introduce a different approach. As a result of the interdisciplinary work of engineers and psychoanalysts a functional model of the human mind has been designed on the base of psychoanalytical theory. As result this work describes the first version of this model in detail and gives an overview on the psychoanalytical theory it relies on.
