Abstract

The present invention relates to a method for controlling the temperature of a system in accordance with a desired temperature curve which is divided into predetermined time intervals. It is the object of the present invention to control the temperature of the system in such a manner that the predetermined and desired temperature curve is observed as exactly as possible. The temperature control method is characterized in that the heating power to be applied to the heating device during one time interval is determined in response to the desired temperature and the heating-up rate of the respective time interval by using empirically determined dynamic heating-up and cooling characteristics typical of the system, that the heating power determined for each time interval is converted according to a calibration curve into a set value for a voltage control device, that the heating power actually applied to the heating device is determined within each time interval, said heating power having assigned thereto a set comparative value by means of the calibration curve, and that, when the set value deviates from the set comparative value by more than a predetermined and set tolerance value within the respective time interval, the set value of the respectively successive time interval is changed in response to said deviation.
