Abstract
Temperature regulation by means of a PID regulation method can be associated with disadvantageous oscillations, overshooting and long control times. According to an exemplary embodiment of the present invention, during temperature regulation of a space, non-linear fuzzy logic is provided which for intelligent temperature regulation uses extensive information from the environment. Such information includes in particular the temperature in the air inlet duct upstream of the heater, and the rate of change in the temperature in the air inlet duct upstream of the heater and in a first cell of the space. In this way, a fast and precise temperature regulating system may be provided which largely prevents or suppresses undesirable oscillations.
