摘要

A method is described for temperature regulation having independent model determination of a process behaviour using the heating process and for determining the transmission behaviour. A first differential element (DG1) determines a first differential variable (RGDIFF1) from the actual value control variable (IRG). By means of a second differential element (DG2), a second differentiated control variable (RGDIFF2) is determined from the first differential variable (RGDIFF1). A maximum variable (MG) is determined by means of zero transition of the twice-differentiated actual value control variable (IRG) and loaded into a first memory (SP1). This value forms the multiplier for a first constant factor (FA1) located in a divider (TE1). From the result and from the first differentiated control signal (RGDIFF1), a difference (DIFF) is formed, which is monitored by a second trigger (TG2). A time constant (T1) is determined in such a way that a switching value of the trigger (TG1) stops a timer (ZG1) started at the beginning of the control process in the event of a difference (DIFF) less than zero, the instantaneous content of the said timer being multiplied by a second constant factor (FA2). The time constant thus determined is made available to a parameter block. IMAGE
