Inversion of the temperature dynamic

Popis výsledku v původním jazyce

Waiting for the state of the equilibrium is important for correct values measurement. Time needed to reach this state is various and can be counted in seconds but also in minutes. This can cause some troubles in industrial processes. Therefore sometimesit can be sufficient to estimate what will be the value of the temperature in an equilibrium state with a proper uncertainty. Estimation of this value can be done by inversion dynamic calculation. Dynamic properties of temperature sensor can be approximated by linear model with distributed parameters. Solution of adequate parabolic Partial Differential Equation (PDE) depends on thermal properties and sensor geometry. Analytical solution is known only in particular cases (infinite wall, infinite cylinder, sphere, etc.). Numerical solution using Finite Element Method (FEM) is also possible, but it will consume computing time during simulation and parameter identification. Therefore, both trivial sensor geometries and FEM are not very usef
