Abstract
A temperature controller (1) for a temperature control mechanism (M) arranged for heating of a device (2) is described. The temperature controller (1), includes an input (3) for a temperature signal (Y), an output (4) for a control signal U for controlling the temperature controller, and a first control loop mechanism (CLM1) can output a first predicted temperature ({tilde over (X)}) of the gas surrounding the device. The temperature controller also includes a first model ({tilde over (S)}) of the thermal properties of the device, a second model ({tilde over (M)}) of the thermal properties of the device, and a second control loop mechanism (CLM2) can output the control signal (U). The input (5) of the first control loop mechanism (CLM1) is provided with 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 the input (5) of the second control loop mechanism (CLM2) is provided with the difference between the first predicted temperature ({tilde over (X)}) of the gas surrounding the device and the temperature signal (Y).
