Mathematical model for considering the change in heater capacity for proportional temperature regulator of the hybrid-film microthermostat

Abstract

The numerical modeling of two-dimensional non-stationary temperature fields of thermostatically controlled substrate for proportional temperature regulator of the hybrid-film microthermostat in view of change in heater capacity caused by instability of feeding currents has been carried out. The method of final differences is used together with the scheme of splitting along the coordinates and the trial run method. The mathematical model of definition in change of heater capacity for the proportional temperature regulator of hybrid-integrated schemes is offered, allowing providing stability of work of the automatic temperature control system.
