Claim 0:
1. A temperature controller for a temperature control mechanism (M) arranged for heating of a device, which temperature controller is configured to receive an input for a temperature signal (Y) corresponding to a measured temperature of the device and generate a control signal (U) for the temperature control mechanism, wherein the temperature controller comprises:
a first controller (CLM1) configured to receive an input and generate an output including a first predicted temperature ({tilde over (X)}) of the gas surrounding the device,
a first circuit ({tilde over (S)}) configured to model thermal properties of the device, wherein the first circuit ({tilde over (S)}) is configured to output a modelled temperature ({tilde over (Y)}1) of the device based on the generated first predicted temperature ({tilde over (X)}) of the gas surrounding the device,
a second circuit ({tilde over (M)}) configured to model thermal properties of the device, which the second circuit ({tilde over (M)}) is configured to predict a modelled first temperature effect ({tilde over (Y)}2) of the temperature controller on the device based on the control signal (U), and
a second controller (CLM2) configured to output the control signal (U),
wherein the input of the first controller (CLM1) includes the temperature signal (Y) from which the modelled temperature ({tilde over (Y)}1) and the modelled first temperature effect ({tilde over (Y)}2) have been subtracted, and
wherein the input of the second controller (CLM2) includes the difference between the first predicted temperature ({tilde over (X)}) of the gas surrounding the device and the temperature signal (Y).
